IPhone 3GS to iPhone 4. I just bought a iPhone 3GS the day before the iPhone 4 was announced. Is there any way I can return mine with the money going towards the iPhone 4?
I'm assuming this is old as the iPhone has been out awhile, but no there is no return policy with Apple or AT&T.
IPhone 3g wont work with universal dock it says in the box iPhone iPhone 3g and iPhone 3GS and comes with the connectors but it says this accessory is not made to work with iPhone?
restore your iphone completely...
What iPhone case has a warranty that if the iPhone breaks they will replace the iPhone?
None that is currently on the market. You should have your phone insured through either home content insurance or specific mobile phone insurance.
