http://androidforums.com – Hey guy so today I decided to move back to Stock TouchWiz and after I updated to Jelly Bean I heard that someone found an update with Premium Suite with Multi-Window (I've tried Metropolis) and so I went into settings and bout device and update but it says that my device is modified and cant check for updates when I'm clearly on Stock MetroPCS Rom. Can you guys help me with this? Thanks :) (General)
