As of right now ONLY AT&T carries the iPhone, they are on Edge coverage. BUT as you have probably heard, Verizon will be releasing the iPhone4 this February 2011. They are on a cdma network, as well as Sprint. It IS a possibility that Sprint could want in on the iPhone obsession, but lately Sprint has been looking into more Windows based phones. So it's unlikely that iPhone will be released by them, at least not anytime in the near future. It may be possible to jailbreak one to Sprint after the Verizon release but that's the only real possibility.
No because even if it is unlocked sprint works on a CDMA and AT&T works on a gsm signal it's like trying to use AM on FM radio only
Now, with the new iPhone 4S it is theoretically possible for the iPhone to be used on any mobile phone network worldwide. For GSM usage (I.E. Sim Card) the iPhone must be unlocked, and a MicroSim must be placed in the iPhone to work. For CDMA use, the iPhone must be flashed to a network, and then additional steps will most likely have to be taken in order for the iPhone to work. If you go to a professional phone store, that flashes, and unlocks phones, then they can do this for you. Also, if you plan to use CDMA, you must get a CDMA iPhone 4S, like one from Sprint or Verizon, then it may be flashed to another CDMA compatible network, or unlocked for GSM use.
What network does sprint use? I know Verizon uses cdma network
No. Different technology. ATT is GSM and takes a sim card. Sprint is CDMA and uses internal programming. Completely incompatible.
No, Credo is on Sprint's network, which uses CDMA. AT&T is GSM. You can jailbreak and unlock the iphone and use it on any GSM network that uses SIM cards however. T-mobile is one option that comes to mind.
no its HSDPA sprint or Verizon or both are cdma
Sprint and Koodo both use the CDMA system so the phones are compatible with both networks.
yes
no
No, You cannot use reliance CDMA sim card (or) any other CDMA card sim card on Apple iphone 4s. Any GSM Sim card will work on factory unlocked Apple iphone 4s but not CDMA sim ONLY IN INDIA.
Yes, it is now. THe iPhone 4S is actually both GSM and CDMA.
obviously not. Att uses GSM technology while sprint uses CDMA.
