i am going to update my 2.1 to 2.3 but i have some questions, hope that you can help me out. im currently on rooted 2.1 with link2sd, if i would like to update to 2.3, do i need to unroot it? and for the apps that i have link to sd, do i need to unlink all of them before i do the backup(using Titanium Backup)? how i want to re-link the link2sd app to my partition sd after i update to rooted 2.3? your help will be much appreciated! Thank you!
