need help Jailbreaking my unlocked 3gs iPhone
Hi, I just baught a 3GS 32Gb Iphone and it's already unlocked but not jailbroken ( no cydia installed ), model number is MC133B and it's also Old boot.
I was wondering if i jailbreak my iphone will it be locked again? and how can i check if it is factory unlocked.
Note that the IOS is 4.3.5 and BB 05.16.02. that's why i'm worried about jailbreaking it coz if it's locked i will be stuck in this unlockable baseband and i'll have to upgrade to BB 6.15 and loose my GPS which i don't want to.
Is this a good question?
