I recently upgraded my 9800 to the latest OS that was leaked last week. When I was searching for the setup option for BIS I noticed that this latest OS has BlackBerry ID managing options included. This is the first time i’ve seen this included in the OS. A few months back we had seen leaked version of BlackBerry ID that was extracted from an OS for a different device. This version allowed me to simply logging with my current BlackBerry ID without having any problems.
Am not sure if this has been there before but first time I have seen it.
Update Thanks to Roy, he explained that this is not the case, but it is probably due to me using BBM 6 read the comment by him below.
