The cost will depend on who your mobile phone provider is so ask them. It should not be overly expensive as its not the latest model of the iPhone.
No.
$200 with a two year plan
Yes the iphone 4 is better so you should upgrade to the iphone 4.
If you have the iphone 2g(the one with black and white back cover),then the answer is no..But if you have iphone 3 or 3gs,they will let you upgrade the phone to iphone 4 as long as you pay for the new iphone 4. Hope this Helps. And by the way,if the iPhone is Jailbroken,or unlocked,then they won't let you upgrade it. so make sure you restore your iphone before you trade for a iphone 4
Is there enough internal memory on your iPhone??
If you've been with AT&T for atleast a year it will cost you $200 and a two year contract.
Yes they do but remember to upgrade to the latest iOS version 6
Yes,but it costs $600 for the upgrade fee..my sugestion is that you just cancel your current iphone contract for $150,and get a iphone 4 for $200 plus the activation fee,and you will have a iphone 4 for $350 instead of $600!
Extra info: I have Terminal, A few emulators Installous and a few ringtones. If I upgrade, what will happen to these things?
The Verizon iPhone 4 is listed at $449.99 when purchased without a contract. When one signs a 2 year contract, however, one can receive the phone free.
you can have an iPhone unlocked provided it is not subject to a contract. You will need an unlocking code from the network if it was on a contract. it is best to have the phone unreleased by the network then you can upgrade the operating systems without problems when updates are available.
A lot but you can go to Best Buy or ATT store to find out
