Since Im not married to Cingular, I decided to switch to T-moble to get 1000 minutes for the same price. To check if my phone worked (i thought "of couse it does dummy, its a GSM"), he gave me his sim and I inserted it into the treo. We, the treo frooze every time!!!!!! The salesperson said that t-mobile is using the new international sims in this market.

Any Ideas!!!!
