Palm has leaked official photos of its Treo 680 and 750 smartphones with Cingular branding on them. The Treo 680 is a successor of the 650 and it's a low-end device based on Palm OS, but info on specs is scarce and unconfirmed. It is expected to feature 64MB RAM, a VGA camera and no 3G capabilities. On the other hand, the Treo 750 is the Cingular variant of the recently announced 750v model for Vodafone. The US version will probably have almost the same specs as the European one, featuring quad-band GSM/EDGE and tri-band (850/1900/2100 MHz) UMTS capabilities, but it's still not certain whether HSDPA will be supported. Also, there's info on pricing and availability for now.
