I'm still on V2 until *228 works and then ill worry bout it. Things are damn stable for me and I don't see a need for any other touches till update prl and meid.. then ill be happy. I don't even mind the Chinese left in some places. It doesn't effect my usage.
I thought that v2 had the same issue with *228. A phone fix was posted. Did you use that to fix your *228? If so and you have it you can use it again to fix v3.1 ! I just did this. You lose the original MIUI phone interface graphics when you apply the fix.
