It seems that Palm is preparing to release Treo 800w. A photo of an email between Palm and the agency shows details about four phones, including ”Zeppelin” which could be Treo 800w. According to this data, this phone will feature co-locating WiFi and radio, like no other Palm handset launched until now. Another phone reffered to as Centro 685, a variant of Centro 690 Sprint-version, could be released by AT&T.
