How do I reset iPhone 4s data setting for at&t?

Find data back from iTunes backup because when you have synced your iPhone with iTunes, your iPhone data and files are to be automatically backed up. If you cant access the data or backup file follow http://www.apple.com/iphone/ and Apple Customer Support .

Contact the store where you purchased the iPhone, and pay them to "unlock" your iPhone. Then, any SIM that you insert will be accepted & recognized.

Yes you can. Walmart sells the package for about $60. Comes with 1 month of service. Make sure you don't cancel your old plan until you go with straightalk. When you activate Straightalk, they take your phone number from them. If you're at&t make sure you have your account number handy when you switch. Good luck.
