Hey silentkill - welcome to the forums!!
I don't have experience with your phone, but have spoken to another staffer about this and he gave me this
link that may be of use to you.
I have also had a bit of a look, to see what I could find - a lot of people are reporting that a restart of the phone has solved the issue you are having... ok... it was actually with the EVO 3D, but I guess the same logic would apply to your phone?
Let us know if this sorts you out
