My Sony Ericsson T610 phone sucks. It keeps crashing, the battery will drop from 3/4 full to empty then it will shut off, and it has a hard time charging using the OEM charger. Maybe its the firmware or its just a crappy phone, either way I want something else. I would prefer a flip phone with bluetooth, doesn't have to have a camera (but most do now). I'm currently using TMobile so it will have to be unlocked or for Tmobile.
