Upgrading to 4.2

[Dinkie]

Hi

I'm currently using 4.1 and I want to upgrade to 4.2. I have loads of programs from cydia that I will lose once i upgrade. Is there anyway that I can back up cydia related programs and install onto 4.2? Is there an easy jailbreak out for 4.2? I've read on various forums that people have been having problems jailbreaking 4.2.

Also i just reformat my comp and i copied the whole itunes folder. What files/folders do i need to add to the new itunes folder so that all my purchases from itunes are recognized.

Pkgbackup can help back up cydia apps. Greenpois0n is untethered on all iDevices on 4.2.1 grenpois0n.com Not sure about the itunes folder question though.

what are the differences with tethered and untethered?

Tethered means that when ever you reboot your iPhone in anyway then you would have to plug it into your computer and reboot in a tethered state, its just a huge hassle. Untethered is the exact opposite.
