Oopsies. It looks like Cingular might have accidentally leaked some information on several of its upcoming smart phones: the Cingular 3125 (a.k.a. the HTC Star Trek) and the HP iPaq hw6900 series (the iPaq hw6920 and the iPaq hw6925, to be specific). The trio of smart phones are listed on what looks to be a mail-in rebate form for the carrier, and though the final prices aren't listed, the hw6920/6925 will have a $50 rebate, while the Cingular 3125 will have a $100 rebate. If the rumors are true, all three models are due to drop next week. We'll see if this actually pans out, but in the meantime, you can read more about the devices here.
