I had the same issue with my Touch. It's either a small break that is causing the LCD to leak or the digitizer slightly pulled away. I'm on Verizon so this doesn't necessarily apply to you but I went into a store, they saw there was no other physical damage and the water sensor hadn't gone off and then they shipped me a new phone 2-day. I would hope Sprint or BB would give you the same service for a defect like that.
