Hi all
I have a 3GS, 3.1.3 jailbroken with Spirit, modem firmware 5.12.01, new bootrom 359.3.2. I also have the SHSH backed up prior jailbreaking.
I've been reading various sites for months about how to upgrade to 4.x.x but can't find an article that fits my situation. I want to upgrade to 4.2.1 (I read 4.3.3 may not be as stable as 4.2.1) but I'm not sure what I need to do to remove the old jailbreak to update to 4.2.1. Every article has some catch, or is for a specific spec I don't have. I don't want to turn my phone into a brick by accident.
All I want to do is upgrade to 4.2.1, restore my paid apps, contact list and settings, and then jailbreak that and hopefully get Cydia back to the way I had it prior.
Any advice is appreciated!
