Let it be known however, that due to FCC rules, all new phone antenna, not just the iPhone's must be placed as far from the user's head as possible. This explains the bottom mounted antenna. Of course it's going to cause reception issues; somewhat. The FCC is trying to save lives, not phone calls. - Sucks, right? Many iPhone users in the past have complained about dropped calls when holding the device at the bottom, this is no different. It's always best to hold your phone away from the antenna. Duhh.
