Hello all! I have an original iPhone that I've been rocking with for nearly two years now, completely legally on an iPhone plan. It's still a great phone, but it has some nagging letdowns, notably EDGE and the fact that it's a 4gig iPhone. I have a friend who obsessively upgrades, and obviously has the 3GS now, and has his old 3G laying around. I'm considering buying it, but I have a couple of questions first: 1. If I buy his 3G, unlock it, and then put my 2G's SIM in it (using the original iPhone's official AT&T plan), would I be able to get 3G speeds? 2. Would Visual Voicemail still work on the new phone? 3. Would AT&T send the storm troopers to my house and haul me off to their secret underground torture chamber? I'm rather excited about getting his old phone - it's a 16gig (and 16 >>>>> 4), and 3G would be really nice! We were gonna get together soon enough and do all the unlocking to his phone anyway, but I was just curious if anybody had any ideas about it. Any help with this would be appreciated. Thanks much!
