If you're a GO Launcher EX user and the recently updated WidgetLocker isn't your thing, then you may want to check out GO Locker to get your lockscreen mod fix. The initial release hit the Market earlier today -- I took a few minutes to play with it, and, while it's not as polished as WidgetLocker, it's still a very nice option. The fact that it integrates directly into GO Launcher EX is quite nice, too; of course, this could also be a negative since it can't be used as a standalone app.

Even if you're already a WidgetLocker fan, GO Locker is still definitely worth checking out -- especially when you consider the price.
