Hey all, First of all, I'm glad to part of this forum. It seems to be the most informative one out there. I'm hoping that my factory unlocked Iphone 4 shows up today. It'll be my first iphone after many years with windows mobile, blackberry, and android. I was just wondering if anyone else is using an IP4 on TMO. Are there any issues (other than trimming the sim card) that I need to be aware of? Thanks!
