Congratulations guys !!!

I downloaded the new version of iOS and is perfect, thanks for incorporating the export and import of private key, now I'm using Bither.

In gratitude I have donated 0.1, wish it had been more, you are doing a brilliant job.

I take the opportunity to ask, when a signed transaction will your servers or do you use blockchain? (https://blockchain.info/pushtx).

Thank you very much for your great work!
