I'm looking to switch from my Verizon Treo 600 to a Cingular Treo 650 (I don't get service at my house with Verizon but Cingular works). The best I've seen so far is $399 on here (Treocentral.com) with a $50 mail in rebate. It also offers the data for $19.95 for unlimited (on Cingulars site I think it's $24.95). Is this the best out there right now?
