OP if your 3GS was manufacture later than week 35 of 2011 the iPad baseband won't work, do NOT flash it on it.
iPhone Dev Team said:
Owners of newer 3GS iPhones must not flash the iPad baseband. The iPad baseband will not work on 3GS iPhones built later than 2011 week 35. You have a week 35 or later device if your serial # starts with xx135.
Hi guys,
Thanks a lot for your responses. According to a web site, my iPhone 3GS was manufactured in week 38 of 2009 (Serial #: 84938MK63NP).
Thanks,
Optimus
Is there any possible way to unlock this phone though?
I have the exact same thing. FIRMWARE: 5.0.1 BASEBAND: 05.16.05
I have jailbroken the phone. Ultrasnow is supposdly not compatible with my baseband yet. So I searched online and the only other way I could find would be to upgrade the baseband to 06.15.00. When I try to do this by "Installing ipad baseband" in redsnow, it says something like ERROR! no sucessful firmware download after 60000 ms!! giving up..."
