Is there any way to get rid of the preinstalled apps? Amazon mp3, city ID, etc. They always seem to just be running in the background. Maybe just some way to shut them off? Will I have to root my phone to do that?
Yes, you will have to root your phone as these applications are usually found in the /system/app/ folder. I suggest you just rename the .apk files for now to something like <file>.apk.bak
