If the glossy, fingerprint-collecting back panel of your new Nexus S
is getting you down, you could always do worse than a DIY soft-touch alternative. xda-developers member mhaedo
took matters into his own hands and used a few coats of Plasti Dip
to make it more grip-friendly.
After masking off the camera window and the NFC antenna, he gave it four coats inside and out (so as to avoid any peeling edges in future) and ended up with something debranded and a whole lot more tactile. Best thing is, it should simply peel off when you're tired of it, so you can sell the phone on afterwards.
