I must say that of all these phones, the Wildfire S is my favourite so far.
Granted the ZTE was fully hackable, but just felt cheap, the Desire HD was powerful, but after several months of use, the size of it got on my nerves. As of a few days ago, I flogged my HD and went for the Wildfire S.
While less powerful than the HD, is a lovely sized phone, sits comfortably in the hand, runs gingerbread very smoothly and is a pleasure to use (looks great too).
Obviously, the phone is VERY new at the moment, and from research, there is no FREE way to root it at the moment. But hey, Im sure I can live without screen-captures and a few unwanted apps for the time being :-)
