I'm running iOS 5 beta 3 and after being through these betas, I love the notification center but I'm just missing too much from jailbreak .. So I'm wanting to downgrade to the last iOS I had before the jump to 5, which was 4.2.1 ... I'm currently downloading the ipsw for it, so really I'm just wondering if it's as simple to install as it is every beta? I just do the option + restore and select that ipsw? And viola, I'm back on 4.2.1 and can jailbreak again? Do I need to downgrade my iTunes, too? ... This sounds easy enough, but I have a feeling it's not that easy ...
