I doubt it only 5 people only next to the model (and only me and another guy on the models stream). Could you try again?
Now it loads... the 'You need flash' page. I pledge 5 BTC spending on the girls once i can watch them on my iDevice. |

Wouldn't load on my iDevice because of flash. Now doesn't load at all. Overloaded?

Congratulations! Thanks for sharing some statistics. Keep up the good work.
Looking forward to move to the states in less than 2 weeks so I can better use your services.

I agree that we need this, and will see if it can be added without cluttering up the UI

yes, many clients (light clients) do this. downside is a central point of failure (in your example blockexplorer.com) and privacy issues. Most of the android clients do it this way. Running a full blockchain-verifying client on a phone is overkill already and it will probably get worse in the future. The important thing is that your light wallet should allow you to be in control of your private keys. This way you can always eject and go for another solution if the server that backs it is unresponsive. Blockchain.info and BitcoinSpinner (possibly also Electrum?) allows you to do so. |

Just checking. Bought a new phone and transferred my wallet nicely - then uninstalled BitcoinSpinner from the old phone. That gets rid of all copies of the secret key in the old phone, correct?
Short of literally wiping the phones storage system, there's always a chance of the key being left behind. I'd spend the money to a new wallet. Both Android and iPhone have in my opinion a much more secure application model than ordinary desktop computers. Applications are sandboxed, and only share stuff that is explicitly declared. This is what allows you to install a bunch of crap games and remove them again, without risking that they clutter your device with useless stuff. Compare this with for instance Windows, where you may get all sorts of strange behavior over time and a messed up registry BitcoinSpinner uses app-private storage for all its data (including private keys). Whenever you delete the BS from your device all data is gone along with the sandbox it lived in. |

I got that startup bug again. Launching BS I get a black screen with just the title bar. Pressing the 'back' button on my phone takes me to the main screen and then everything seems to work. So its really not a big issue, just a minor inconvenience. Using V0.5.3b
While this is a minor issue, I do have it on my radar. However, I have not been able to reproduce it on my own devices. |

Cheers, it's a great piece of software.
I think we need to document how to send funds easily from desktop to spinner. For me I copied the address to the Android clipboard and emailed it. Can it be shared via the android sharing thing. This ought to be written down somewhere perhaps. This is probably better than using desktop/laptop webcam as I guess QR code reader aren't common on the desktop.. could be a webbased one I suppose.
You can click the textual address on the main screen and share using various methods. I have a 'Start up tip' on my list of features, which optionally shows you a BitcoinSpinner tip (from a list of tips) on startup. This would be a natural place to add this hint. The other thing I guess is that some websites like BitcoinTorrentz don't generate a QR code for you to pay them with. I wonder the best way to generate a QR code off that.
In general I think that Bitcoin on mobile devices is going to be big, and we need to educate sites that support Bitcoin to show QR codes. Another alternative is to let the site use a bitcoin URI, which both MultiBit, Android Bitcoin Wallet, and BitcoinSpinner accepts. If you add this to your web-page you can click on them and launch your wallet: <a href="bitcoin:1Bmc9QwQgmuNWTxo5PjzPWeSF4d3aHx6hH?amount=1.00">1Bmc9QwQgmuNWTxo5PjzPWeSF4d3aHx6hH</a> Why do all this? Well, perhaps it's easier to keep a phone secure than a desktop and I kind of like the QR code thing and I love BitcoinSpinner that much!
I totally agree. The application model used by both Android and iPhone is much more secure that your standard desktop computer. Apps are sandboxed and cannot touch each others "private parts" |

I love the simplicity.
One thing though,
I emailed the private key to myself because at the time I didn't know how to email the QR code. However, if I use that private key to try to generate a QR code it won't restore.
I guess the QU backup codes contain more than just the private key.
Is there an online wallet that can import a private key? It's a small amount just for testing
There was a bug with the 'copy to clipboard' button that caused your Bitcoin address to be copied instead of your backup code or private key (the QR code however is correct). This has been fixed in the latest release 0.5.3b. The backup/restore QR code is not your private key, but contains information on how to derive your private key. The private key that you can export under advanced settings allows you to evacuate from BitcoinSpinner. It is not recommended that you use this to experiment with spending from two wallets having the same keys at the same time, as it may cause accidental double spend attempts that may result in inconsistencies. The private key is in SIPA format and can be imported at for instance Blockchain.info and I guess also mtgox and armory for sure. |

Bump for one of the best new Bitcoin services yet!

BitcoinSpinner has been around for some time now, and a lot has happened since it was announced back in November. In an effort to be more open I would like to share some BitcoinSpinner stats with the community. - Total installs to date: 816
- Active device installs: 503 (people we did not uninstall it again)
- Total installs with actual BTC in them: 303 (This is the one that really matters)
To be honest I had expected more active users when I started out. On the other hand, 300 is not bad at all, and the number is climbing slowly but steadily every day. Since the theme for BitcoinSpinner is ease of use, and getting up and running really quickly, I expect to get a large influx of users once Bitcoin hits the next level of adoption. We are not there yet, but I am ready. I would be very interested in getting some stats from other Bitcoin services. So, how is it going?

finally, newest version runs on 2.1. Many thanks, Jan! this is awesome. some remarks: - my screen is 320x240. is there anything below "transaction history" button on main screen? the button is 2/3 visible and no scrollbar appears
- on the "send bitcoins" page, there is a scrollbar (generally it's good to have one), but if you can save one pixel somewhere, it would disappear, so that might be a slight beautification for small screens
- how to get a new receiving address?
thanks again for taking the effort to "port" to android 2.1 Thanks for the feedback. The only thing under the 'transaction history' button is a 'use at your own risk' notice. I'll test on an emulator with 320x240 resolution and see if I can make it all fit and avoid scrollbars. |

I just received this mail from someone who does not seem to like OKPay. I could imagine a lot of bitcoiners receiving something similar. I have never registered with OKPay. Maybe they are mailing everyone whose email was leaked from the MtGox hack. ------------------------------------------------------------------ From: OKPAY < support@okpay.com> Date: Wed, Apr 11, 2012 at 3:24 PM Subject: OKPAY is SCAM! To: XXX removed by OP XXX Cc: XXX removed by OP XXX Hello, I want to warn you that OKPay is scam payment processor. They were fine while I was making small transfers, but as soon as my balance reached 11000 USD, they blocked it. And it's blocked since August last year. Stay away from OKPAY! |

First of all thanks, I'll be donating.
Thanks! I think possibly an essential feature might be something to stop someone picking the phone up and emptying your wallet. If anyone would be interested in helping with that here's a code snippet for some swipe code: https://github.com/chriscoyier/Slide-to-UnlockPerhaps the most simple implementation might be a swipe pattern required for sending a payment and if the user forgets the pattern the password can be reset by a 30 hour time delay, hopefully giving the chance to recover coins in the event of a stolen phone. Something like this has come up before, and it is on my list. I am planning to add a simple and optional PIN code that you can enable in settings. If enabled, the user would have to enter the PIN when: 1. Sending coins 2. Disabling the PIN feature 3. Changing the PIN 4. Making a QR-code backup 5. Exporting the private key The PIN is not meant for securing the private key stored in the app. The key is stored in app-private data on the phone, and you can only access it if you gain root access on the device. Getting root access is not trivial. To secure the private key against root access it would have to be encrypted with a non-trivial password of significant length. This would in my mind make the app very cumbersome to use. The PIN prevents someone from grabbing your phone and leech it of coins, which is a very useful feature. The best solution would be to not have the private key on the phone at all. You can achieve that by having several wallet backup QR-codes printed on laminated paper. One QR-code for petty change and another for larger sums. Whenever you need access to the fat wallet you restore it from a QR-code, do your spending, and restore your slim wallet from a QR code on top. This way the fat wallet is wiped from your device. |

Are there any plans to release the server code so that users can set up their own servers and redirect Bitcoin Spinner to use that server? If not, is there any plans to add the option of using Tor, so that even the presence of such a client cannot be determined?
There are no plans to release the server side code at the moment. However this may change going forward. Regarding connecting through Tor. I don't think it is trivial to do that, but I may be wrong. In the end BitcoinSpinner was designed for simplicity and ease of use. I have to be very careful when adding complex features that only a handful will use, and I think Tor would be one of those features. |

Version 0.5.3b is available: - Support for Android 2.1 devices. Until now only 2.2 and newer devices were supported. This has so far only been tested in a 2.1 emulator, as I don't have a 2.1 device. Molecular has agreed to do thorough testing.
- Translated to Finnish. Kudos to Tomi Blomberg.
- The 'copy to clipboard' bug has been fixed. Previously your Bitcoin address was copied to clipboard when clicking 'copy to clipboard' on pages showing private key or backup QR-codes.
Enjoy |

My android device is certainly not managed by my carrier. My carrier provides access to their network but can do nothing on my phone. My carrier has no software running on my device, and the worst thing they can do is not providing access to their network. They have the same power over my device that my ISP has over my desktop computer. Nothing.
You cannot compare M-pesa with Bitcoin.
If that's the case (i.e. they may have access and you don't even realize it), then you're an exception. Most people have a phone where the carrier has exceptionally deep access to the device. It continues to amaze me how paranoid people are on this forum. So what you are saying is that when I have a android/iphone that is reset to factory defaults and I then insert a sim card from some carrier, then the carrier can get control of my phone. You cannot be serious. Guys, bring out your tinfoil hats. |

Molecular. You are right on all accounts.
I have tested the latest changes against a 2.1 emulator (I don't own a 2.1 device myself) and everything seems to work. The next version should be 2.1 compatible. My hope is thay you will thoroughly test on a real device.
Cheers,
Jan

I believe keeping keys private / locally is HUGE!
I had replied to another thread but that hasn't had any response there so I'm reposting it here as it applies to this thread as well (well, it applies to most every mobile app which can spend bitcoins): What I am concerned with is "the Linode problem". All these mobiles are managed devices. They can be fully controlled by someone other than the owner of the device. Yes, they are managed by the carrier but possibly that carrier has people that cannot be trusted or, just as bad, has people who don't maintain secure systems themselves such as what reportedly is what happened at Linode.
The importance is thiis. An attack that defrauds M-Pesa's customers en mass means Safaricom figures out at some point that there's a problem, halts all affected systems to prevent further losses, and in the end eats some, most or all of the customer's losses. A similar attack through the managed services of the mobile network to steal bitcoins from mobiles means just that the individual mobile user alone loses out. Just like how Linode disavowed any responsibility to Slush, Bitcoinica, etc. for the tens of thousands of bitcoins lost, Safaricom would likely maintain the same position.
So, this is a fundamental question -- is the practice of storing bitcoin private keys on the mobile something that exposes it to too much risk to where it shouldn't even be considered? i.e., bitcoin apps for mobile need to be under the same model that mobile banking (like M-Pesa) uses?
My android device is certainly not managed by my carrier. My carrier provides access to their network but can do nothing on my phone. My carrier has no software running on my device, and the worst thing they can do is not providing access to their network. They have the same power over my device that my ISP has over my desktop computer. Nothing. You cannot compare M-pesa with Bitcoin. |
