I had high hopes for the sensation after loving my MyTouch4G with Cyanogen. I thought the Sensation would get the same love. Instead I had a phone with terrible battery life and never any stable roms, and hardly any real dev support.
I hate to be "that guy" and post this, but I've moved on to an iPhone 4s & seeing two months later that the sensation development hasn't moved one bit, i'm glad i Did.
Good luck all.
Running HyperSensation v1.5 and I promise that my Sensation runs circles around your iPoop4. Great battery life (ever heard of waiting a full charge cycle or two after flashing?), never crashes, tethering works, speedy, and lightweight.
However, you getting an iPoop was a good thing. One less person on xda complaining!
