Rom Upgrade - No info Lost

[evoodoo]

Hi,

I was wondering if there's a way to upgrade Rom's without losing all the information on my windows mobile device - info like, how I have my front screen set up, which tabs I keep and which I remove from Sense, which programs I install, etc..

Thanks
Eric

PS - I tend to use Energy's Rom and upgrade semi-frequently, I would think that sticking to one set of roms would make the upgrade without loss of information simpler.
