I have a refurb'd Inspire 4g that I just bought (a week ago) already unlocked(sim) Came stock with 2.2 Froyo and of course AT&Ts bloatware.
12 hours later(internet sucks in Afghanistan) I am root'd and running GingerBread 2.3.x
Of those 12 hours 11.5 were downloading the 3 needed pieces of software
.net 4, HTC Sync, and bubbly 1 click root tool
I don't have the luxury of waiting on AT&T to push the update as I'm not in the US and besides I don't need their crapware.
