Hi,
after updating, Mycelium tells me that my Android 2.2 phone is unsupported due to a bug in random number creation on that OS version.
Could you share some technical details so I can estimate my risk? (or did I miss an announcement somewhere?)
Since I'll be switching to a new phone in a few weeks anyway (Christmas is just around the corner) I could probably live with avoiding to create new transactions and just initializing from the backup once I have the new phone.

there is a bug that leads to android 2.2 being unable to multiply big numbers _sometimes_. previously this mostly just lead to wrong TX being generated, that were rejected by the network. annoying, but no huge risk.

now with HD wallets it is possible to generate a wrong address from a seed that has no matching private key. this is bad. therefore, quit using it Smiley we had one case where a user reported this, and we strongly think android 2.2 was the reason.
