Looks like the FCC docs for a “Slide Dual-band CDMA Phone with Bluetooth/WLAN” made by Sharp have shown up on the FCC site. The model number, PB20ZU, is unsuprisingly close to that of the Turtle.
Of course, nothing juicy like external shots until 180 days after the filing, which would put us out at early August. I imagine the Pink devices will be out by then, or at least for Microsoft’s sake I would hope so.
For the record, the FCC ID is APYNAR0066.
