Yesterday we showed you that awesomely slick Sony Ericsson Walkman slider that we know only as the Shinobu. Today we submit to you the Sony Ericsson M610i (codename: Lizy) via the FCC test pages. Presumably, the older brother of the Sony Ericsson M600i Symbian OS qwerty-smartphone, the Lizy boasts full UMTS 3G on tri-band (900/1800/1900Mhz) networks. Details from the FCC approval are slim to, well, none, but if you want some speculation on the M610i’s abilities, check our previous coverage. We can assume that the M610i will address all the shortcomings of the M600i.
