(but note if you don't have access to an official sim, you'd need to search for a method to hacktivate...) i don't really recommend doing this, but if you're desperate and/or enjoy experimenting with your phone, you could give it a try. good luck!

I used sn0wbreeze to make a custom ipsw, then back on my mac, used redsn0w to enter pwned dfu mode (I see the "expoiting with limerain" etc, and it appears to succeed). tried doing option-restore in itunes and select the ipsw, but it goes for a while then gives error 1601. I guess 1601 should be about USB? I'm using the same good Belkin USB cable I always use, no problem jailbreaking this phone several times before. I even tried a different cable, still the same 1601 error. any ideas? fyi, at first I tried just using redsn0w to do an on-the-fly restore to the 6.1 ipsw with preserve baseband, it seemed to work, but then it was stuck in recovery mode and recovery fix didn't work. shouldn't matter though?

IMEI unlock is best if you can do it, but if not then ultrasn0w is working on 5.1.1 for unlock. check cydia to see if you have the proper blobs saved there, and also downgrade your baseband, no-one should be using 6.15.00 on a 3GS anymore...
