Ok, I did search the forums however I don't see anything quite like my situation and I wanted to confirm before doing. I basically followed this post: http://forums.macrumors.com/showpost.php?p=8050698&postcount=21 I currently have the 2g with NOcontract using att on the $20 plan. I read the process for sim swap to keep my $20 data plan on 3GS, but have a couple questions. 1. When I buy the phone, I assume I can buy online and get the discounted phone price? 2. I read that this may work better for 3g -> 3gs swap since they are more similar? I know it works for 2g -> 3gs, but do you think they will eventually switch my plan over since I'm on 2g data plan? 3. I don't quite understand the IMEI process. Do I just call customer service and get it switched AND have to unlock my phone?? OR do I just need to call them and switch IMEI and that's all? Thanks guys! There is currently a $50 off when buying online, so I wanted to buy online instead of go to store.
