You want to buy one? Just get an android device or a jail broken iPhone (but I'd recommend staying away from iPhones if you can).
got a htc a8181 android but it will not run it
Running Android version 2.2.2
Webkit 3.1
Hmm, is that the latest version? Have you tried contacting blockchain's customer support to see which version might work?
Mine still works on my iPhone 3s as I downloaded it well before they took it down, but I won't be going back to Apple once this phone breaks.
