Had Sprint before with a Sanyo 4900 for 5 years - loved it, worked beautifully. Would have another - downside, no one else uses them - and I wanted to kill Sprint. So went to Cingular, got the military discount + 100 bux off on the 2 phones + the mail rebate. I use my phones till they are dead, while I don't expect these will last as long as my last 1 (which i never changed the battery and always got 4 hour talk time and 7 days between charges), i'm hoping for a better experience.
Time will tell...
