Query: I'm waiting for my 4th Treo...

Think twice before you buy this. My first and second Treo 600s had identical problems, where they couldn't find the network for some reason, and the answer button wouldn't work. I got the first one in February 05, and the 1st replacement in April 05. The second replacement came a week later. Now, this one has developed these orange pixels [http://discuss.treocentral.com/archive/index.php/t-51494.html], and Sprint is going to replace this one. I will note that Sprint has only replaced my phone with refurbished phones, so I can just imagine that I'm just waiting on my replacement phone, which is just Joe Schmoe's broken phone that has the same darn problems. I just hope that all of these problems keep happening within the warranty period. If you can, buy the warranty.
