Hey guys, Most of you are probably better with this stuff than me, so please try not to be frustrated by my lack of understanding. Keep in mind two things: I have an iPhone 3G, and I am eligible for an upgrade. 1. Since iphones are moving to micro-sim, and I have a 3G with a regular sim, will I need to go to AT&T to update my sim first? 2. Do I pre-order through AT&T or Apple? Or either one? And would I get the new SIM and upgrade discount if I go through Apple? I've never done this before. Any info pertaining to the above would be huge. Thanks!
