So you think that you’re suffering from a serious case of butterfingers, where most of your devices tend to slip away from your hand by accident? Well, that would just mean you will need to get a rubber-based iPhone 4 case for that spanking new smartphone of yours, but alternatively, do you fancy a DIY job? That is possible if you don’t mind sticking some skateboard grip tape to your beloved iPhone 4. Yes, you read that right – skateboard grip tape! This makes the hottest selling phone (perceived, anyways) on the planet less slippery compared to the glass and metal cases, although your palm might feel rather grated after a while.
