Well like any phone these days (or media device for that matter) your a fool if you dont invest in a screen protector (of course in my opinion) but with all the different various eBay vendors to buy from you just never know what your getting or the quality of what your getting.
I took a leap of faith and bought two of these screen protectors from: NEW XtremeGUARD BlackBerry Torch 9800 Screen Protector - eBay (item 220654279900 end time Sep-13-10 11:22:15 PDT)
(2) of them for just under $5.00 shipped isn't bad to try
They showed up 3 days later. Their warehouse was close to me, I think Arizona if I wasn't mistaken.
These protectors are really thick with really scared me since its a touch screen phone but hasn't affected the sensitivity of the phone. Other than me putting the protector on wrong and NOT following the very well written detailed instructions, the protectors are by far the best I've ever seen or use.
Just my .02 for what its worth.... It is a little hazy as the directions say it will for a day but even here again, its worth to protect your phone. I would expect the hazyness to improve per the directions.
I give them a 9-10 so far
