11 iPhone Gotchas
Off-limits battery
While we're on the subject of the battery, it's worth noting that, like the original iPod, the iPhone has its battery enclosed in a superslim case among tightly negotiated electronics and behind a top surface of glass--reducing the chances of a DIY battery replacement to next to nil.
