Hello, I've been lurking the forums for a while, but I finally registered as I am about to buy my first iPhone. I'm not new to Apple technology. I currently own an iPod Touch 2nd generation, and I'm typing this on a MacBook Pro. I have T-Mobile as a provider, and I am not interested in switching. I know that I will only get EDGE speeds, but I will usually be using WiFi if available and only use cellular data in places where I can't find WiFi. I am looking to buy an unlocked 16GB iPhone 4S, MD234LL/A. I am in the US and I have a few questions. 1. If I buy it online, will I need to send it back if I need to return/exchange it? Or will the Apple retail store be able to handle it? 2. I actually prefer to buy it at a retail store because the next state over does not charge sales tax. If I ordered online, they would charge me sales tax based on my address. The unlocked iPhone 4S is unavailable for reservation or in-store pickup on the site. Will they be offered in the retail stores? I tried asking Apple, but none of the reps knew (understandable since they keep the info on lockdown). I know that the iPhone 4 was offered unlocked earlier this year. Were those available in stores? Maybe that can help me predict whether the 4S will be available in stores unlocked? 3. Is AppleCare+ available in the store?
