Hello- I have a question. I'm currently on Sprint and planning to get the new apple telephone in the next month or 2. However due to a workplace discount I plan to switch to ATT in the next year. When this happens I would like to just switch my phone over with an unlock and a sim. Does anyone believe that an unlock will ultimately allow dual-mode CDMA-activated phones to ultimately be used on a GSM network? I realize that I could also just sell the phone to subsidize my switch... Thanks.
