I have wanted to upgrade my Treo for sometime now. I have a 300 model. I was looking around on ebay and found that some with bad screens were selling around $50 and then a replacement screen was another $50, so I was thinking of doing this over the next couple of months and then Saturday someone put up a Treo with a bad screen and comes with a replacement screen for $50. I emailed the seller to get the phone ESN number and then called Sprint to make sure I would be able to activate it and sure enough it was good to go. I should have the phone sometime later this week. I will post how the surgery goes with replacing the screen. Here is the auction if anyone cares to see it http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5873438069 and you can read about the features here http://www.palm.com/us/support/handbooks/treo/treo600sprint_DS.pdf It is still an older model, but quite an upgrade from what I have now. The current model is the 650 and the newly released 700w that now uses Microsoft Pocket PC for the OS.
