iPhone 3GS firmware 05.11.07 upgrade to OS4 - possible?
Posted on 2010-09-23
i've got a handset iPhone 3GS, which has firmware 05.11.07 and is running pre-4 OS with the help of blackra1n
can this phone be upgraded to OS4? and if so how?
my other 3GS has an older firmware and PwnageTool does the job, but it seems that should not work on 05.11.07
