Thanks for a slew of good advices!
I restored back to my original ROM now, but realized that I don't really need to restore my app data, but good to know that titanium is able next time.
Thanks for the advice about the sms as well, but isn't there any way to restore the MMS also? Not that it's important, but curious if it works.
And yes, I use Myphoneexplorer as well(excellent program for syncing, especially if you're slightly paranoid about putting all your info in googles cloud), but don't think they have figured out how to store mms yet(don't think it worked on older SE-devices as well). So:
1. Is there any way of restoring MMS?
2. Will my contacts be restored with pictures and all if I export them to the SD-card and then import them after switching ROM(as mentioned, don't want to do it with google contacts if it's possible).
3. Doesn't Market keep track of what apps you've installed and uninstalled? I'm back to the original ROM now, but pretty certain I couildn't see what apps I used to have when I logged into market with the new ROM(but same google account). Last time I used market, I while back, I could check what apps I've uninstalled in market, but I can't find those in market now either. Just the apps I've already have installed. Did they remove that feature in the latest updates?

Just restored my original ROM, so you're saying I could do your trick now(double negatives always confuses me :-))? Thanks for the warning about mucking about with system based settings, didn't occur to me at all that restoring sms could be harmful.
