Hello.

Currently have an iPhone 4 running 4.1 with limera1n JB. I've been thinking of updating to 4.2.1 now that GP is out. Is it possible to upgrade without losing all my JB apps? I'm assuming an update to 4.2.1 will render all the JB apps inoperable, but will they work again after the GP jailbreak? I have done a lot of customization to the phone which I'd like to not have to re-do everything if possible.

Thanks
