Sony Ericsson rearing a 'Julie' Windows Phone 7 slider in the lab?

Our latest Windows Phone 7 gossip stems from the juicy Chinese grapevine. Rumor has it that Sony Ericsson's now testing a WP7 device -- possibly a first for the company -- codenamed "Julie," which sports a sliding QWERTY keyboard and a capacitive multitouch screen about the size of the X10's. Ah, this sure brings back touching memories of the firsttwo WinMo Xperia sliders. Apart from the processor being clocked at 1GHz or above, little else is known about this unborn baby -- no dates, no photos ('tis our mockup on the right), but we won't question this tipster who also brought us SE's "Shakira" and the peculiar 5.5-inch Android device. Anyway, given SE's track record, it'll probably take six more months of gestation before Julie pops out.
