I bought a 3GS on eBay $100 was going to give to my sister early bday gift. she's not as techy like her nerdy younger brother lol so I figured she would get good use out of it. I just wanted to know can I ask AT&T to unlock it as I did with my iPhone 4s ? Or can it only be unlocked by jail breaking? There's about 6 months left on its 1 yr warranty from apple. I'm using straight talk on my 4s is there a prepaid company that seems to work best with the 3GS ? Thanks for any info ideas etc :)
