I got a Qualcomm 2760 from Radio Shack for $100, down to $50 after the Rebate at the begining of August. I got the rebate in the mail about two weeks ago, only 6 weeks after activating my phone. I also switched plans, so switching plans does not screw up the "must have phone activated for 1 month" thing.
I get 1000 min for $29.99. 200 anytime minutes, 200 nights and weekends, 600 bonus nights and weekend minutes, with nationwide longdistance/roaming (on the Sprint Network). Yeah, kinda disproportionate, but I use it mostly at night, so it works out great for me. So far, my service has been exceptional.
