I recently bought a GS3 from Radio Shack and I returned it. I planned to buy an iPhone 5 the same day but they said i was ineligible for an upgrade. I called AT&T and they said it could take up to 3 days and it depended on radio shack. Kinda bummed because right now, i have no phone. Anyone have experience with radio shack on these matters? How long did it take? The guy who did my return seemed a little confused just going through the return process...
