Newbie here: I purchased an unlocked GSM Galaxy Nexus and have it running on tmobile. Since tmobile doesn't sell these phones here, how do I keep up with the newest version of ICS? It came running 4.0.1 and says there are no updates, but don't the updates get pushed thru from the provider? And am I wrong in assuming tmobile won't care about updates until they affect a phone they sell? I did start to read about rooting, but I don't think that's something I want to get into. Any insights would be appreciated!
