yup it's a hardware issue. Mine started with the space bar, soon after it turned into texting like this "hhhowwwwwww arrrrrrrrrre yyooouuuu?", and after that the light went on but no response from the keys. If you are still under the sprint warranty you don't have to go through TEP and you can get a new one in a few days. You even get to keep your old battery!! Well, if they don't send you a refurb.
