Iphone 4- Activation

[arif123]

I'm currently an iPhone 3gs user and thinking about getting an iPhone 4. If i do upgrade, will my old iphone 3gs get de-activated by apple/att? Will it have any other effect on my 3gs? Can I give it to my sister who currently has a non-iphone data plan?

The phone itself will not be deactivated. The SIM card inside it might be deactivated (someone else might be able to confirm this).

But if the SIM is deactivated that doesn't matter as you can give your old phone to whoever you want, even if they don't have a data plan. They just take their current SIM and put it into your old phone.

You can get the iPhone 4 and your old 3GS will become unactivated.

Then you can go into an AT&T store and tell them you want to give your old 3GS to your sister. They will give you a new sim for your 3GS with your sisters number and activate the 3GS. Her line will need the 15$ data plan added but that should be it.
