Amazon is selling the Blackberry 8800 for $100. They're dropping $375 right off the $499 price, and then giving an extra $25 off in the form of a rebate. The catch? They want you to signup for new service of course and stay with Cingular for a couple years. It's still a great deal. Here's the fine print.

"Conditional $250 Equipment Discount Included: Your price paid includes an equipment discount of $250 that has been provided to you in exchange for either activating a new, non-substitute line of service or renewing an existing line of service with Cingular, and your agreement that, for the 181-day period following such activation or renewal, you will: (1) pay your balance due to Cingular each month and otherwise maintain your account in good standing; (2) not disconnect this Cingular line of service; (3) not transfer this equipment to another Cingular line of service; (4) not change your Cingular service rate plan to a lower monthly service rate; (5) not use this line of service to replace an existing account with Cingular. If these conditions are not met, you hereby authorize Amazon.com to charge your credit card $250 as reimbursement of this equipment discount without need for further approval."
