Hi everyone. As you can tell, I'm a little new around here, but I hope you can still help me out. I recently bought an iPhone 4 on craigslist, and found that it was still under warranty. Its on the latest firmware, 4.3.3, and I unlocked with gevey sim and jailbroke it with redsn0w. HOWEVER, the iphone does have a small crack near the bottom left hand corner in the back. Also, the home button is sometimes unresponsive. Also, I lost the original sim card tray...(Gevey comes with a custom one and I misplaced the old one) I am planning to restore and genuinely activate with a old AT&T card before I go into the shop. I want to claim the warranty! I want a shiny new iPhone! I don't have AT&T service however.. Also, like I mentioned, I am missing the sim tray and the there is a small crack on the bottom. Do you guys think that Apple retail store will help me out? It is under warranty until November. Any tips? I was told to say that I have to reconnect the wifi every time I turn it to sleep.. Any TIPS???!!
