I tried to install the Fastcoin Wallet 3.39 for Android found here:
http://www.fastcointalk.org/index.php/board,61.0.htmlThe install failed and my phone's file explorer indicates that the app name is Bitcoin Wallet 3.30 (while I currently have Bitcoin Wallet 5.23 installed). That explains why it doesn't work.
The package name is de.schildbach.wallet which is the same as Bitcoin Wallet as well. The icon is for fastcoin. How can this be?
