i admit after all that waiting, you'd expect PR1.2 to be better. but i dont see anything wrong with the update. only see improvements.
recaller seems to be working fine with me. same with most other apps. except conversations inbox which doesnt show up but theres a new update that fixes that.
i had enhanced kernal installed but it crashed my ph with 850 oc and again at 800. ive uninstalled it since and havnt seen any problems yet. so maybe all the problems alot of people are experiencing could be related to the custom kernal
