It looks like Sprint has stopped selling the Galaxy Nexus online. Could we see an LTE-enabled LG Nexus 4 coming to Sprint soon? I hope so.
It's hard to believe Google would bother at this point in the N4's life-cycle.
Although there is part of me that just wants to buy a GSM N4 and give T-Mobile a try in my area. Probably would get better data speeds until Sprint's LTE deployment is done, and even then...
