I could barely read your incomprehensible mess, but from what I could tell you were an idiot and upgraded your phone's iOS.
You're probably on 4.2.1 now. If you need the unlock, you have to install the ipad bb when you jb. After you've done your jb, you install ultrasnow to unlock the phone.
Whenever you have to restart your phone or the springboard in Cydia, you will have to boot tethered. You need the computer and redsnow to start your phone.
From now on, you can no longer upgrade via itunes. You must use a custom firmware. Otherwise, your phone will go wonky like when you screwed up before.

What is the baseband on your 3GS? Ultrasn0w only work with baseband lower than 05.14 or if you install Ipad baseband 06.15.

If you are using T-Mobile, then you need to switch off the 3G. Go to "Setting", "General", "Network", then turn the "Enable 3G" to off position.
