If you’re scratch-prone, consider the iWrap—front-to-back protection for your iPhone 4. (For anything non-iPhone-related, I’d suggest these.)
My husband is one such user, and he’s a fan of the full body coverage that iWrap offers. The film is virtually invisible, low glare and comes with a lifetime warranty. Full disclosure: make sure you’re working on a surface devoid of lint and follow installation instructions for best results!
This week, take $5 off the complete iWrap solution.
