running into problems

I have been modelling the phone using a relatively low poly-count. As a result of this I started running into problems when applying smoothing groups particularly on the back of the phone where I have some detail to model.

here are my results.




I was not happy with this so I deleted the current back of the phone and spent quite a bit of time, a few hrs in fact, re-modelling the back from scratch. This time I used a very high poly count. This gave me a lot more control and freedom for desing and makes the end result look a lot more realistic. as you can see there are no issues with stretching or with smooting groups.
