Picked up my refurbed Treo 600 this morning. Not sure why it takes these guys like 30 minutes to do an exchange, but it did. Anyway, I have it now.

It has the blueish tint but by playing with the contrast and brightness you can make it less obvious.

So far so good. No network search problems but let's see how long this one lasts :-)

Phone info is as follows:-

Software: Treo600-1.10-SPR
Hardware: C
PRL Rev: 10023

Fingers crossed here.
