A new update has rolled out for the Xbox 360 which added some 'backend Stuff' according to Major Nelsons blog, and the only new feature added was an Xbox Video rental feature. We have updated and tested Xkey's with the latest Dashboard update 2.0.16747.0. and they are working fine. We can not see any reason for you not to go ahead and update your Xboxs with xKey fitted. For those of you with LT 3 flashed drives you can check the thread here with confirmed drives that have already been tried and tested if you want peace of mind before updating.
