If you've ever worried about accidentally switching cell phones with a friend who has an identical model (I sometimes worry about this, my sister and niece have the same phone as I do) then you can always get a customized cover like this lovely example of a custom metal plated Nokia 3310. Seriously, NOBODY will want to take your phone home if it looks like this.
You upload up to three images, specify what finish and design you like, and Customizedphonecovers will send you a laminated, scratch-resistant metallic cover that snaps onto your phone. They can also customize just about anything, including your toilet seat or temporary tattoos.
The mobile phone covers are about $8.
