sorry about the late response. I'm currently trying to root my phone. It's had Froyo 2.2 on it since the update came out. I wanted to put Gingerbread on it and generally just have my pc recognize the phone. I've tried different cables, all the possible drivers, uninstall, reinstall, kies mini, the list goes on and on. I've plugged my phone into three different computers, one with Win7 in which I get no recognition in regular or USB debugging mode, one with XP, no recognition there either, and one with Vista in which USB debugging works but that's it. My problem is that when I put the phone into download mode, then the Vista PC doesn't recognize it. I'm pretty much damned if I do and damned if I don't. Samsung and T-mobile were no help and I've scoured the internet for weeks trying to solve this problem. I know one thing, Samsung will be lucky if I ever buy another one of their products. This is maddening! If anyone can help, I'd be EXTREMELY grateful!
