iPhone 3g 5.0.1 old bootrom 6.15.00
Hello, recently got a 16gb iPhone 3gs old bootrom (was at 4.1 BB 5.16.02)
Just upgraded BB to 6.15.00 and firmware to 5.0.1. The phone is jailbroken, cydia works (cydia has 4.1 shsh saved)
The issue I seem to be having is getting my t-mobile sim card to be recognized by the phone. ultrasn0w has been installed, phone was rebooted.
redsn0w 0.9.9b8 (for jailbreak)
latest itunes downloaded from apple (upgrade to 5.0.1)
used firmware 5.0 with redsn0w
Version 5.0.1 (9A405)
Carrier: AT&T 11.0
Modem Firmwaer 06.15.00
Phone shows No Service instead of carrier
Network: Not Available
Help Would be appreciated :D
Update: Turned airplane mode on, as soon as it was turned off Invalid SIM replaced the No Service on phone, took SIM card out, back in now says no service again. Also "Could not activate cellular data network" popped up.

This was the only method that worked for me since ultrasn0w didn't work. Just download the ultrasnow files and DiskAid to access the files on the iPhone and just drag and drop the unlock files to the phone. restart the phone 2 times and you'll see the T-Mobile service. I guarantee you.
