Is it common when trying to do the signature on blockchain for the skript to stall and be unresponsive?
Wanted to try this out but keep getting "unresponsive skript".

I never had that problem, but I also dont use blockchain very often. Its probably best to contact their support about this. Might just be an server load issue.

You are correct, you cannot. There is no such feature. Realised this today when I was asked to sign a transaction after I gave out one of my Xapo addresses. Had to pluck an address from Electrum instead and sign that one.

The wallet of Xapo is actually very featureless. You cannot even store contacts or anything like that and you also cannot see your old addresses once they have been used.

Really wish they will put some work into their wallet as I use it quite often for the day to day stuff and sometimes it gets a bit frustrating using it as you are forever copying and pasting.

Might have been building up to that. Was not like that at the time I was trying to achieve a signature. Go figure the day I decide to finally do it.

I think blockchain.info in available now, and you can go and sign a message

Think the issue is on my end. Will have to wait till I upgrade and get a newer mac.

Nice tutorial dear. Now I know how to sign a message properly.

[shorena]

I added several wallets to the list of those that can not be used to a sign a message. You might notice that they are all for iOS 7.1.2 which is the latest available iOS version for an iPhone4. I have access to such a phone over the weekend. If you have any wallets that do not require iOS 8 (e.g. Mycelium does) you want me to look at let me know here or via PM. I have some more on my own list (Hive, YardWallet, Zebpay, Coins)[1], but the Wireless for the phone seems a bit unstable. My personal priority here is Hive as its the only wallet I know about that at least in some versions allow you to sign a message[2].

[1] some of these might not actually be wallets, but they turned up when I searched the store for "Bitcoin Wallet" and did a bulk install.

I think that you should include also that you can not sign a message from coinbase android app, there is no option for it.

Great, after i saw the last post i checked on my phone if it is available to sign a message or not, then came here to tell , it is really limited-access on the phone, you can not do everything like in website.

Added signing with Bither 1.3.7.1. I did the screenshots on an Ubuntu 14.04 Desktop system, the look and feel might be slightly different on other system, but the buttons should be at the same spots.
