i'm running xtrROM 3.0.3. all of a sudden this afternoon, my phone shut itself off, then turned itself on. it would connect to 3G, then repeat all over again. i've tried to remove the battery and waited about 10 min, then put it back in, and it still does the same thing. i didn't update anything today, didn't install anything new at all. i was using it just fine this morning. any ideas? i figure my last resort would be to restore from a previous nandbackup. but that was a month ago, i'm hoping i don't have to do that.
