I am eligable for an early upgrade and didnt know if i would be able to sign up for a 1yr commitment instead of 2yrs. My currnt contract ends the end of november 2011 but they've emailed me stating i could upgrade early, thing is i only want a 1yr commitment and not a 2yr. Do they allow early upgrades for only an additional 1yr agreement or do they require the 2yr.....thanks
