Ok so this is my first post and I would like to say that the information I have found on this website has helped me understand my Iphone a lot so just wanted to say thanks!

Ok now on to my question:

I just bought a locked/unjailbroken 2g iphone off ebay and jailbroke/unlocked it using winpwn 2.5 on 2.0.2 firmware. I'd like to upgrade to 2.1 when pwnage is available for it.

What exactly do I need to do to keep all my cydia/installer apps when I do the upgrade?

I have downloaded a lot of these apps and it would be a serious bummer to go through all that downloading and searching again.

I have searched the forums but don't quite understand. Could anyone please help me on the exact process? ( or at least what has been done in other cases like upgrading from 2.0.1 to 2.0.2)

Thanks in advance guys!
