So my iPhone 3G has 5 hairline cracks along with dust under the screen, and I'm very confident that Apple will replace my iPhone if I took it to a store. I plan on buying the new iPhone that will be coming out sometime this summer as well. So my question is, can I go in there and get my iPhone 3G replaced and then buy a new iPhone all in the same visit? I know it probably looks selfish that I want to walk out of an Apple store with two "new" iPhones, but I plan on selling my current gen iPhone 3G once I get the new one this summer and listing it as "new" dramatically helps in the resale value. They're going to give me a dirty look when I tell them I'd like to buy a new iPhone right after I get my 3G replaced, but is this permissible? Danke.
