For 4 months I struggled with sprint. I could not make a call on my account due to no service every time I dial out.
Then my Treo started only dialing out when it was plugged up,(what a f???ing headache I had with this.) Took it back to sprint and they swaped me a new one.
So to all you treos who use sprint service and you are having this problem, if it's not a year old take it back into the sprint store and get another one and don't wait 4 months tring to make it work like I did.
Since I replaced it I have had no problems so far
