I have an Iphone 3gs that is currently running 3.12. I tried to upgrade to 4.1 a few months ago but couldn't activate so I was forced to roll back to 3.12 again.
Will any of the new tools activate my phone for me? or bypass the activation procedure?
I understand that I can activate with any old AT&T sim card but I don't have one to use and haven't been able to find one.
Do you rely on an unlock? If so, update to 4.1 via custom firmware created in Pwnagetool on a Mac or sn0wbreeze on Windows (I believe this will be released shortly). You have the option of hacktivating with those programs.
If you use AT&T and do not rely on an unlock, I believe limera1n and greenpoison hacktivate also, so update to stock 4.1 and then use either one of those programs to jailbreak and activate.
