Can i use a unlocked iphone 4 on tmobile?

Can i buy a unlocked iphone 4 and use it for tmobile? Like and still be able to use the internet and apps and all that?

Yes if you unlock you will be able to use it on any service provider.

Yes. One problem, though it may be fixed soon, is that you wouldn't be able to use 3G on T-Mobile due to mis-matched frequencies.

Yes you can buy an unlocked iPhone and use it with Tmobile or with any network you wish. As how I look at it, an unlocked iPhone means you have the freedom to use any compatible network of any provider and insert any SIM card compatible. Once an iPhone is unlocked, you are allowed to use carrier other than its official carrier.

  • Will an unlocked iphone 4S work for tmobile if it isn't factory unlocked? I want to get an iPhone 4S and my friend has the iPhone 4 unlocked but i'm worried that if i get it non-factory unlocked it won't work. My uncle tried to do it a couple of months ago and apple said that if it was factory unlocked every time the phone shut off or died it would reset. I was just wondering if the same thing would happen if it wasn't factory unlocked? So if I get it unlocked everytime it will shut off it will reset? That is what i'm worried about.
