Something appears to be wrong with the Ringer Switch - the phone think's it's on mute - if I push and hold the switch to the left, the volume will work but if I let go it goes back to mute. I can physically barely touch the switch and it'll go back to volume but the moment I let go it is back on mute. If I jam a toothpick between the case and the switch, therby keeping the switch pushed to the left the ringer works fine.

Phone is less than a year old, has never been dropped or mishandled in any way. Any ideas?
