anyone into custom roms i suggest avoiding the ICS version of MIUI big time
i used it for a week, had to wipe and go back to gingerbread
a few minor issue i had
random voice drop out, i'd be talking to someone then they couldn't hear me, required reboot
unlocking phone turned on the LED light and it wouldn't go off without reboot
sending a text message, it sent every message twice
half my apps didn't work on it
the phone regularly shut itself down
the music app when i paused it shut down the phone
so just a few 'minor' things
