Hi All,
I just joined this group today, so its nice to be able to contribute on my first day of group membership, but I just returned from the Samsung website which tells you the status of open source OS updates for your Samsung product I have just downloaded and am planning to install now, the file:"SPH-M950_JB_Opensource.zip" which tells me that I am downloading the JellyBean!
See the above posts (By jimmy422, and James319) for the Open Source download link and the process to get your device to look for, download and auto install the OS upgrade (JellyBean)
GO GET IT!!
