I jailbroke my iphone 4 for the first time on 4.3.2 using redsn0w

I downloaded a bunch of apps etc.
now i want to upgrade to 4.3.3
but i don't want to lose my apps etc.
so what is the process to upgrade and rejailbreak without losing apps?
my baseband is 04.10.01

thanks in advance from a noob

to clarify my wife is making me do mine first and i don't want to lose all this info setting etc. i have on here now with all my repos etc. and i tried to search for this already, but came up snake eyes... again probably my fault but i appreciate any help!

Surprised you couldn't find a thread about this, it's pretty much asked at least 3-4 times a week. In any case, plug in your phone, right click, tell it to back up. Upgrade to the latest iOS and your data won't change. Your choices for backing up your Cydia packages are relegated to a few pay apps in Cydia (AptBackup, PackageBackup, etc.) I've never had much luck with them so I just write down the 10-15 packages and queue and install them after jailbreaking. Now that Cydia allows package queuing, this usually only takes one cycle of downloads to get all of my Cydia packages back.

In any case, this has been discussed many times on the forum and there are other threads with more detailed info, so I'm closing the thread.
