Appreciate help...someone gave me an original iphone (16GB) that they had purchased unlocked for Tmobile. It has been working great for me. But now I'm interested in adding some of the cool apps and can't figure out what I need to do. I upgraded iTunes to 8.0.2.20 but was told that if I updated the firmware (which itunes was prompting me to do) my unlocked will be undone. I was able to download apps to itunes now but it isn't allowing me to add them to my phone. Looks like my firmware is 1.1.4. Appreciate any help. I'm not techy but I follow directions well
