First time posting on a forum, so excuse me if I dont do it correctly. Ok, so I got my DX about a month ago. As I read through forums I found out that there was no easy(at least to me) way to completly backup you phone. So I rooted and got Titanium backup to do just that. No I want to try to install some custome roms. So I did some research on installing custom roms, and read on a thread that some system files where not safe to backup and restore with other roms. So my question is. 1. What system files are safe to transfer from rom to rom. 2. If I dont want to install a app that is on my backup, can I exclude it when restoring apps on new rom. 3. This one is just out of the blue, when I went to Verizon, a rep. told me that one of my apps was "pulling internet". Is there a way to know what apps are accessing the internet without permision, and is there a way to know which app is using alot of your resources. I hope I was clear on my questions and thanks to everyone in advance.
