Premgenius Posted October 24, 2010 Share Posted October 24, 2010 I'm looking into getting an iPhone 4 16GB but I've heard a few things that I would like to clarify. If I get an unlocked iPhone 4 I have to activate it via iTunes the first time if I change the SIM do I have to reactivate via iTunes or will it work without any reactivation?

Guest Posted October 24, 2010 Share Posted October 24, 2010 The iPhone 3G S had to be reactivated if the SIM was changed. As far as I'm aware, this is still the same with the 4. Link to comment Share on other sites More sharing options...

neo1911 Posted October 24, 2010 Share Posted October 24, 2010 Once your iPhone is unlocked, it needs initial activation with any sim other than the one its locked to. Simply connect it to itunes to display a message which says "Your iPhone has been unlocked" Once that is done, you can put in as many different micro sims in it and no need to activate. You will only have to activate is when you reinstall/restore your phone firmware. But will work with any micro sim as your phone was hardware unlocked.
