Thanks to all the people give me valuable advices on my previous discussion about unlocked iPhone. Now, I have another question in regarding to GSM and CDMA network. Let's say I bought a cell phone from T - mobile, which is used GSM network. After I unlock the phone, can I switch it to Sprint, which use CDMA network? Can I unlock those cellphone and switch them around different network?
