I got a 650 1 month ago and have constant problems with reception. I like the Palm functionality, but no one can hear me and I constantly cut out. So bad I have to switch to a land line. Please respond if you have had success or not had success with the 7750 from Sprint. Does anyone ever ask you to repeat what you said or complain about not hearing you?
I am in the same boat as you. Been testing the Treo 650 for three weeks and I have the same complaints about the reception and other issues. I plan to return it this week. I am also looking at the 7750 since it is also offered by Verizon. I think I want to stay with Verizon, not happy with the Sprint support or coverage. Have you tried the 7750 yet?
