Could mystery handset on Sony Ericsson page be P3i?

We love when handsets pop up in places they aren't supposed to, and Sony Ericsson happens to have done just that with the handset outlined in red in the pic above. Nothing is known about the phone pictured -- or if it isn't just a placeholder or other error -- but some speculate that it may be the rumored P3i. While the image is a bit dodgy, it appears that it sports some type of joystick-like d-pad and seems thick enough to be a slider. We've absolutely no idea when or if this handset will be announced, but be sure we'll fill in the blanks as soon as we're able.
