I recently purchased a T-Mobile Pulse (or Huawei U8220) in October last year, and have been playing around with rooting the device, installing custom firmware and generally hacking the phone into submission.
I started a wiki page for the phone over at MoDaCo forums covering all the skills and tricks I picked up along the way. Other MoDaCo users have also contributed to the guide, so I can't take all the credit.
