Palm's sieve-like reputation for keeping a lid on unreleased devices continues to the current round of Treos in the pipeline, and we're happy to feed the fire today with possible specs of the upcoming "Hollywood" accompanied by the obligatory hastily-snapped shot (blurred here to protect our valiant tipster). Though we still don't fully understand the relationship between this bad boy and Cingular's upcoming "Nitro" and "Lennon," it's said that we're looking at an antenna-less GSM Treo rocking Windows Mobile 5, 128MB of internal storage, and a 412MHz XScale core, all gussied up in a package "considerably lighter" than its 700w stablemate. If our source is accurate, all this goodness will drop sometime this September -- not a moment too soon for Treo fans on GSM carriers getting a little jealous of their CDMA brethren. Naturally, skepticism is in order here, but the engraving on the device lends some validity to the thought that it's a prototype, and this all lines up pretty nicely with Cingular's roadmap, no?
