Device was originally-planned to launch in late 2012 with Ice Cream Sandwich.
Sony France has said the Xperia V has been delayed in order to offer consumers the Jelly Bean update upon launch.
The company confirmed it's pushing back the launch of the 4.3-inch smartphone from the latter stages of 2012 to the end of January in order for the device to ship with Android 4.1 Jelly Bean from the start.
Previously, the Xperia V was due to launch with the 4.0.4 Ice Cream Sandwich version of Android, but consumers voiced their concerns on using an OS that is a year old.
In addition to the phone's delay, a small off-contract price cut has also been announced. The phone was originally set to be priced at €549, but it'll now retail for €529 ($704 to $678).
The Xperia V features a 4.3-inch display, dual-core 1.5GHz processor, 1GB of RAM, 8GB of internal storage, a rear 13 megapixel camera, front-facing VGA camera for video calling and a 1750mAh battery.
A total of 2.7 percent of Android devices run Jelly Bean, while Ice Cream Sandwich is installed on 25.8 percent of devices.

Except that 4.2's out now....
When this thing was new, the email client didn't work, the whole interface (Android 2.1) was slow as h*ll (despite the very nice hardware inside), opening the calendar would open a random day, and the battery lasted just barely a single day. I have no faith in the Xperia line after this disaster of a phone. Even worse, I could have gotten an iPhone 4 for almost the same price!!
this is obviously a manufacture defect, that's why warranties are invented, my X10 works fine except you're right that battery life is it's weakspot but it can't be that bad brand new
