Its a site I have used for a while and I found this while poking aroung. I used it on the H6315 and the only issue is after applying the multiple phone skins you have to soft reset. No Biggie.
Also I found a one handed SMS writer application that is average... but could be good when you are driving (be careful) to send a quick one handed SMS message using the standard numerical tap method. It works without a hitch....
