@rfc2822 FYI, on https://icsdroid.bitfire.at/download/ the amazon link is wrong: Points to Google Play store instead of amazon store.
Thank you, we will fix it soon!
Awesome work, thanks so much! I just send you some money via PayPal as a small thanks.
I solved the problem, by wiping data, cache, dalvik partitions. After reinitialisation and installing the apps, everything works fine again!
Great, thanks for the update!
