Hello. I am on a jailbreak iphone 4, on 4.2.1. bb 03.10.01, unlock with gevey sim card.
I would like to know, if I can update to 5.1.1. and keep the unlock status in any way.
Is anything 100% sure? I am afraid to do this and loose a working phone, but I am getting frustrated with all the apps I can't use unless I am on v5.
And one more question. If I back up, and then I try with any way to update/jailbrake/unlock... can I go back to the backup no-matter what? Or are there problems? Something about bb upgrade making it imposible to go back to my bb, and therefore loose my unlock status?
Many thanks in advance...
