Can Iphone 4 be used with sprint unlocked?

Answer 1

Yes the iPhone 4 currently is being sold on Verizon and AT&T currently but should be expected to be on Sprint shortly. Sadly though only the iPhone 4 runs on CDMA networks as well as GSM. If you are thinking you can unlock an iPhone for Sprint or Verizon that's under the fourth generation like the 1g, 2g, 3g and 3gs, it wont work.

Answer 2

yes you can Verizon now has SIM cards

e: This is patently untrue as of 7/22/2010

edit2: Verizon uses CDMA and AT&T uses GSM, so no. An iPhone will not work on Verizon because the iPhone is a GSM only phone. The only carrier other carrier you can use an iPhone on is T-Mobile.

Answer 3

Generally, these days, phones that can be moved from system to system are GSM phones. Phones that are sold by Sprint and Verizon are not GSM - or they are not GSM on their home systems.

The iPhone uses GSM.

The system that Sprint uses is NOT GSM, so a GSM only phone like the iPhone won't work on Sprint, period, end of story.

Sprint will sell you an "International Phone" that will work as a Sprint phone in the US and will switch to GSM when you are in an area that Sprint is not in and GSM is in. Like Europe, for example.

In some countries, all cell phones use the same system. When cell phones were first introduced in the US many years ago, that was true here. There were two systems, and you paid full price for a cell phone and you could transfer it from system to system. Eventually that changed; phones were locked into systems, and incompatible systems were introduced.

But then much of the rest of the world standardized on GSM and AT&T changed from the analog/digital system they were using here to the GSM system. In the US, national carriers that use GSM are AT&T and T-Mobile.

Answer 4

No.

The only U.S. wireless networks the iPhone is compatible with are AT&T Wireless, and T-Mobile due to technical limitations. Unlocked iPhones can be used on T-Mobile's network with less-than-full functionality (visual voice mail doesn't work, for example). Additionally, Apple will not support unlocked iPhones.

Answer 5

Ultimately yes, but currently no. This is because it was anounced today tht in china, a china mobile carrier unlocked iphone 4 for their network...Google it for the actual story that made headlines

Answer 6

No.

The iPhone uses a different technology (that's more widely adopted globally) than what Verizon and Sprint use for their infrastructure.
