im running 2.9 with everything just how i want it, also apps on sd card too.
what is the best way to upgrade to 3.0 without losing everything?
just download and update - it wont wipe your data unless you do a wipe.
do a naindroid backup before doing it though, just incase, and you can roll back should u need.

Thanks again for your help and I appreciate this must be a really stupid question.
