Registry Question
 

While trying to figure out how to do call tones, I made a failed attempt by changing the registry, and I forgot to make a backup.... My phone is still working, i just need the default values for HKey Local Machine->Software->Mcrosoft->Windows->CurrentVersion->Internet Settings->5.0->User Agent need the defaults for Compatible, Default, Desc, Platform, UA-Language and Version

The main reason that I need these, are because when I load my home page, it says under phone "Unknown Device" and under the sprint site, the same as well... Thanks!
