Should I upgrade?

I would like to know if I update my jail broken ipad1 from 4.3.3 to 5.0.1 will I lose my layouts and Cydia apps. I spent a lot of time setting up my layouts and don't want to lose them. I backup my Cydia apps and layouts with springback and pkgbackup and refuse to use iTunes except when absolutely no other option exists. (ifunbox and transcopymgr)

I have searched iclarified for tutorial for updating jailbreaks but didn't find enough info to determine if the update will distroy my layouts. If anyone has info to allow update of jailbreak to 5.0.1 without backing up with itunes and losing setups please respond with advice.

Thanks
