    Hey everyone!
    I am desperately in need of some help right now as I can't get my iPhone 3GS to restore in iTunes. I had a baseband of 05.16.05 and my serial number digits 3-5 were above 135 (if that matters). Here is what I did with it:

    Right after I bought it, I came home and restored it. After that, I jailbroke it using Redsn0w (tethered). I then went into Cydia, got the Corona untethered package and restarted my iPhone. I downloaded Ultransn0w in an attempt to unlock my iPhone but it didn't work. Since it didn't work, I went looking for videos on how to get an At&t iPhone 3GS with baseband 05.16.05 to work on T-Mobile. I found a video on YouTube that said to open Redsn0w and change the BB to iPad BB which is 06.15.00 so I did exactly what he said. After I restarted my iPhone, it wouldn't let me use it. It said "Plug into iTunes" so I did. iTunes wasn't doing anything so I went to Redsn0w again and this time I pressed "Deactivate" and continued that. Now, it is stuck in recovery mode and I tried to restore it with the original firmware and then the custom firmware but iTunes says,"cannot restore iPhone because of unknown error. (21)".

    Please help me! If I can just get it to take me to the springboard then I can take it back to the shop I bought it from. I just need to be able to restore it properly.

    Thanks for your help!

    Ok, I went into Redsn0w again but this time I clicked Recovery Fix and it turns on now but it gives me a screen that says "Connect to iTunes". It keeps restarting itself and iTunes isn't detecting it.

    Please help!
