After hearing about this policy I encouraged my wife to demand an upgrade from Sprint when the pixels on her 5th 600 started to crap out. Some of the other 600's we received in the Equip. Replacement Program were crappy refurbs or new ones with worse problems.
It should be noted we have been ontime paying customers of a 2000 minute shared vision plan for over 2 years, which gave them incentive to keep us happy. Having a cingular650 to compete with now probably doesn't hurt either!
After getting runaround from sprint phone-customer service, a reasonable store manager granted our request for a free upgrade to the 650 after we declined another lame 600. Patience pays off, the 650 was ordered yesterday for 3 business days delivery w/out using equip. replacement program.
