Just heard that the 2.1 is rolling out for unlocked handsets. My hero is sim free on 3. I'm guessing the upgrade will come across at some point. I bought my hero in October last year and i've never upgraded the firmware. Do i have to update it first? Also how do i back everything up? My contacts info won't be necessary coz they are all tied to my email address on google. Sorry for being thick, but i've never had a phone that could receive updates before.
