Naturally, you'd be worried if the thin business smartphone you owned had another software update available, barely over four months after the first came out (though admittedly one-third of a year is eternity in the smartphone and PDA market).

But the second Motorola Q update (named MOL2) not only comes pre-installed on Verizon Wireless' new Black variant (other Q users can also download and install the update), it apparently applies "great improvements" to existing features. It seems the Q's battery life has been enhanced.

So Q owners out there, download the update immediately. Thanks to Q Users for the heads up.
