Does anyone know if the standard 30 day tech support and 1 year warranty that comes with the iPhone 4 is valid for any iPhone 4 regardless of what store you buy it? I believe when I pick mine up tomorrow AT&T is going to try and convince me that the iPhone has absolutely no warranty at all, and if it is defective the following day, I'm screwed. I'm thinking this isn't true, and Apple would cover all their products with the same 1 year warranty, like a gaming system, it doesn't matter what store you buy your PS3 or 360 from, Sony/MS cover the warranty wherever. The Applecare ($70/year) can be added any time within the first year while it is still under Apple's warranty right? So it probably would make the most sense to add it closer towards the end of the year, rather than right away?
