joanna, I do wholeheartedly agree with my colleague mayer. The only thing that I would further recommend is to follow this [guide|3675|guide] I know, I know my pictures are horrible :-)It was my first attempt ;-) anyhow, the digitizer is really easy to change compared to some other phones. It took me less that 20 minutes, and that is taking my time. I know that you do not have the customer service, but may be by disassembling it you can get it cleaned with some isopropyl alcohol. I replaced two of the digitizers for less than $20 if you can't get them but need them let us know I am sure we can arrange to get them to you ;-) good luck to you
