Sony has released a software update for the PlayStation Vita to fix bugs with the device ahead of its U.S. launch in February. The PlayStation Vita 1.51 firmware comes just over a week after the device was introduced in Japan and fixes an issue that affects progress in NEXT Dynasty Warriors, one of the 26 games available at launch.

The software update is actually the second to come from Sony, if you count the 1.50 firmware, which was available when users first powered up their Vita after purchasing the device. You can grab latest firmware (for those who couldn't wait until February and imported a Vita) through a PC, PlayStation 3 network function, or the Vita itself, via the Settings/System Update menu.
It's unclear whether the 1.51 firmware fixes scattered problems some early adopters reported with the Vita. These include various crashes and gameplay lag, as well as sudden device freezes several users documented on YouTube. Sony, however, denied that such glitches exist, hence why the 1.51 update only mentions the NEXT Dynasty Warriors game progress fix.
Sony's PlayStation Vita has had a solid, yet unspectacular start. In the opening weekend, around 325,000 units were sold in Japan; in comparison, Nintendo's 3DS handheld sold 371,000 units in its first 48 hours. Some 26 titles were available on day one for the Vita, and Sony announced U.S. and European customers would have 33 games available for purchase when the Vita goes on sale Feb. 22 for $250. A $300 3G-enabled version will also be exclusive with AT&T.
Meanwhile, The Verge reports that Sony updated the Japanese PlayStation Store with a couple of new game demos: the first for Uncharted: Golden Abyss, one of the launch titles, and a second for a yet-unreleased game, Gravity Rush, which is set to arrive soon after the U.S. launch of the Vita.
