Selling IPhone 4, question....

[ilivetowin#IM]

So I decided to sell my Iphone 4, because I have 3 lines on my account and the other 2 lines are both eligible for upgrades so I can get another one when they hit stores again.

1.)My question is how do I go about telling ATT I want to go back to my old Iphone 3GS tonight?

2.)And what shall I do to wipe my information from the IPhone 4 and prep it for sale?

3.)I would like to keep my information as is so when I get another IPhone 4 I can transfer it all as is and be right back to where I am now

...Any help is greatly appreciated!

1) I'm not sure, but I assume you have to get a SIM for the 3GS since your current SIM won't work without an adapter.

2) Settings --> General --> Reset --> Erase All Content and Settings

3) Back up your iPhone 4 in iTunes before doing #2 above!

Yeah AT&T will give you a new sim card, just go in and ask for one. They are free.

Just plug in the iPhone 4 and click Restore in iTunes, then restore as new. Everything will be gone.
