I've been invested in Factom since around $3, and it's one of the least hyped coins with huge potential. They have an excellent team, and a very specific goal and target market. In that respect it's kinda like ripple, they have a very specific market they are targeting and very solid business sense combined with technical prowess. I think people saying what Factom is doing doesn't need a blockchain are not understanding how it can be helpful here. I think the main feature of blockchain they are using is that it's tamper proof. So, you can make a record of a mortgage document, and then you can have legal proof that those documents are exactly as they were when signed. I'm not sure how it all works, but I think this is highly appealing to companies to cut down on legal and auditing costs.

I never used hive for iOS, but I recently recovered an old bitcoin hive wallet from mac os, so I may be able to help. If you have the wallet files, and they're not encrypted with a password/pin, then there should be a way to recover them. When you setup your wallet, did you create a password or a pin? The 12 word seed isn't really a password, so much a backup, so you can restore your wallet if the file is lost, but assuming you still have the actual wallet file, you don't need the seed words, just a way to read the wallet.

The desktop hive stored the wallet in a file called bitcoinkit.wallet, did you find any file with that name? It's possible the iOS version stores it in one of the .db files you found, I'd need to dig through the Hive source a bit and see. If your wallet didn't have a password or pin that you forgot, I'd be willing to dig into this a bit.

I recently found a backup of an old Hive wallet (bitcoinkit.wallet), and couldn't figure out how to decrypt/export the private key using available software, so I wrote a small utility. I looked through the hive source a bit and saw it was using bitcoinj, so I did the same and it worked perfectly. I'm not sure if anyone else will find this useful, but I put the code up on github if there's anyone in a similar situation. My code only works on non-deterministic wallets with encrypted private keys, because that is what I had backed up.
