What is the Motorola mystery device on the WiFi Alliance site?

The WiFi Alliance website is second to the Bluetooth SIG website in tipping gadget geeks like myself on impending device launches.  This morning LeakDroid has noticed that a new Motorola handset has just received their WiFi certificate, but what could this device be?  Well for starters the product is listed as MB501 which suggests a higher-end device line than the product numbers of the Motorola CLIQ and DEXT (MB200/MB300).  The Motorola Droid (Sholes) and Droid Eris for Verizon Wireless are prepping to launch within the next week give or take a day so an October 27th WiFi certificate does not seem likely.  This leaves us with two other possibilities, the QWERTY Motorola Calgary or the dual-mode Motorola Zeppelin.  At this point it is far too early to tell, but if the device product number is used on the FCC database we will have device confirmation in no time so stay tuned.
