I've never used screen protectors for my iPhone- I always go with some sort of case (currently using an iSkin Solo on my iPhone 3GS). However, with my iPhone 4 on the way, I'm thinking of making a change. I'm hearing a lot of hype about the Wrapsol Ultra- how it provides great shock protection, how phones can withstand falls while wearing it, etc. etc. Hearing all of that has me wondering- should I get a bumper, should I get a Best Buy case like the Griffin Reveal (+ the Sharpie trick), OR, could I get a Wrapsol Ultra by itself and have that be my case? For those of you with experience with the Wrapsol Ultra, do you feel like it's enough protection for your phone, or would I need to put something on top of it like a bumper? Thanks for your help.
