I had two of those, one for coinbase and one for blockchain, and both worked beautifully until recently.
I had them uninstalled because I had to lend my phone to someone for a time and I did not want any trouble.
now... I went to the store to reinstall and they are both GONE!
Coinbase support says they "do not offer" it. Blockchain.info links this new (and improved) blockchain wallet app in the store,
but it is not working properly. When sending coin it ignores decimal point, so if I try sending 0.012 BTC it will actually send 12 BTC.
It is probably written by some rich dude who does not care about fractions of BTC
Funniest part is that there seems to be an old style blockchain wallet still in store on web site, it is only downloadable as a xap file, but I cant install it, says "your company app cannot be installed".
Looks to me like some Microsoft new policy. Somehow they decided if it is available on iPod it should NOT be available on WinPhone.
I am seriously thinking about ditching this windows phone for good. Do they make problems like this for Android users?
