I bought a treo 650 unlocked GSM off ebay. It still uses the old version of 1.06/5052/0. I have heard horror stories regarding updates. I am in Central America and cannot afford to have major problems down here. I heard a story where the update locked up the phone, requiring going back to cingular to reset the phone. I do use cingular service in the states, but the phone is (supposedly) a generic unlocked GSM phone. So, suggestions???
