    i think there may be more to it than that, check out the guides on unlocking on the wikiGuides.

    Did you put the lockdown file in /usr/libexec first and of course you put the in the app folder also did the 755 thing? Then shut down your iPhone and while off you take out he AT&T sim and restarted the iPhone and then ran the unlock app. So what did look like when you ran the app? This will help out allot. Meaning what did it tell you to do.

    what's not working with tmobile, phone calls, internet, youtube, voicemail...?

    I use AT&T for my service. I unlocked and tested with a friends tmobile sim. so I would not be surprised when traveling and using overseas pre-paid sim card. =)

    I'm not that knowledgeable with tmobile I'll try to help if I can. can you please explain your problem in a little more detail?
