Aha yeah, I did this to my phone
Although I cheated and bought the gems in a big sheet, which I then just cut out in the shape of my phone and stuck on. Took 2 minutes, teehee...
Yeah, there are shops here that specialise in blinging up people's personal possessions. In the window of one shop they have a BICYCLE covered in gems. (I'm not joking about this, either) The prices in those shops are RIDICULOUS as well... but the blinged-up stuff does look awesome.
