Do I need to copy and edit my own preferences.plist or can i use someone else's? (I have copy of mine at work, but am home for weekend. I put a copy of one which I got off of web on my phone before I went home.) Web on iphone is slow as molasses. It has been 48hrs since I requested TMobile Web. I did receive text message from TMobile confirming request. I took sim out of iphone and back in old Motorola phone, and was able to access TZones much faster than web on iphone. So should I go to work and get the backup of my original preferences.plist off my work computer, or can I copy and paste off of someone else's?
