With MWC right around the corner, all eyes are on Microsoft for the launch of Windows Phone 7. Even through FCC troubles this looks like Sharp’s Turtle phone.

People close to the Project Pink have revealed that it is not the star of the collection but rather an evolution of the SideKick. The diagram for the model PB10ZU shows a short, stout device that bears an unmistakable resemblance to the Project Pink Turtle images we saw last Fall. The filing reveals that the PB10ZU packs dual-band CDMA, EVDO, Bluetooth and WiFi connectivity

As Engadget points out, the FCC filing’s details are being withheld until March 29, just after the CTIA conference in Vegas. That conference has been rumored as a potential venue for the debut of the Zune phone. Exactly what place the Turtle will have in the Windows Phone 7 line-up remains unclear.
