To get the MSL # you go to connectbot, type in getprop, and in the mass of info the shows up, look for [ril.MSL] the 6 digit code after that is your MSL #As for streaming applications like Pandora and TuneWiki you'll have to disable Multimedia gateway (new feature in 2.1 rom) .It works fine after that:
