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?

GSm and CDMA are two different forms of telecommunication services and yes there are many cell phone which can run both type of network services ..OK now coming to i phone yes you need to break it code and then you can use it easily .

i tried doing it before but it didn't work but i guess it depends on the cellphone, you could try calling sprint and check if they can activate your phone.
