I just found some good screen protectors for my new Nokia E61 phone. They are by Martin Fields, and seem better than the screen protectors I've had in the past for PDAs and phones. What I like is that the plastic is rather thicker and firmer than the usual plastic; it's like a thin overhead transparency sheet. This not only makes them tough, but much easier to apply (they aren't as prone to bubbles under the surface). Very nice.
