I see this as a mega fail IF like the other HTC Sensation models there are lots of bloatwear apps that can't be removed unless you root it.
I'm not talking about those added by a carrier. These are in a carrier free unlocked phone.
Faceblock, Twatter and many others can't be removed unless you root the device which automatically invaidated the warranty.
The phone bit of the UI is also crap. at least 50% of the time when you hang up a call, it hangs up all well and good but then it automatically redials the number.
My HTC Senastion is being sold on ebay this week. I might get £50 for it.
This is easily the worst 'smartphone' I have ever used.
