AT&T. But you can "unlock" an iPhone for verizon.
Yes. Vodaphone now sells the iPhone.
There is no such thing as a mini iPhone. If there is, it can't possibly be legal on the market with that name.
If your iPhone is unlocked, then yes, all carriers will work. But if it is locked to a certain carrier, then you will have to unlock it using a jailbreak.
4G refers to the carrier not the phone maker ... and the carrier for that phone does have a 4G network...
this depends on the carrier you will be using. the talking and texting part is about the same on att and verizon (~$50). what will vary is the Data. this will be different from carrier to carrier depending on how much you wish to pay for. sprint has their Unlimited everything plan for $70 a month i believe. an iphone 4s will work with sprint in this plan. please keep in mind that the iphone 4s is not a 4g phone on ANY carrier
An iPhone 4 can be purchased at any carrier of the iPhone. And any Apple in-store or online store.
It depends what carrier your on. Most of them are in the hundreds starting at $199.99 is my guess. You can check with your carrier on their website.
In the continental US AT&T has sole exclusivity as the carrier for iPhone through 2011.
Yes, actually it's the only carrier you can buy the iPhone 4 from in the US.
yes, provided the network carrier provides the micro sim required for the phone.
