$69 and change a month after taxes and fees, unlimited everything except minutes (500 "anytime" unlimited nights and weekend). I have the HTC Hero, and somehow I'm eligible for a full upgrade every year, not 2. I still have to sign up for another 2 years, but it seems once a year they change the contracts allowing you a free out anyway (if I had a reason to leave)
Before my Hero I had a Blackberry Curve. The calls on the Hero do sound a little echoy on my end, but that's a phone issue, not a service issue. I'm rarely in a place without signal here in Washington State, and I'm not in the Seattle Metro Area (thank god).
their customer service has always been good to me, if I need to ask them anything related to my account. Just like anywhere, if you're respectful, they'll help you out, or get you to someone who can. For question about hardware, I never go to them, I look on the phone's related forums instead, so I don't know about their help there.
For info on how to get on their new employee referral program, just Google "Russ.firstname.lastname@example.org" and it should take you to his site, where you can find the last 3 of his employee number (383 i think...)
They also offer an Employee Referral program for the internet cards.
