Hey,
I want to upgrade my unlocked 3GS's 3.0 firmware to 3.1.2.
I need to unlock the device again after the upgrade. I'm using a PC running on Windows XP.
I've done a lot of reading but haven't found an answer to this query -
Now that blackra1n RC3 is out & can unlock devices with baseband 05.11.07...should I upgrade to the latest firmware using iTunes & get to the new baseband or upgrade using a custom firmware keeping my baseband at 04.26.08?
I read that the unlock when baseband is at 04.26.08 is more reliable & permanent than the blackra1n JB & subsequent unlock by blacksnow at baseband 05.11.07. Is this true?
Or does Pwnage tool 3.1.4 do a better job at the newer baseband & unlock it without issues by ultrasnow?
I can get my friends Macbook & do it.
What should I do? I need to keep my iPhone 3GS unlocked to use it..so require the best unlock solution there is.
Thanks in advance!
