Best place for the root info and custom android builds for cliq is modmymoto.com. Thedude is working on it as we speak and since I have used many of his roms on my G1 I trust his stuff will be quality.
Been doing research on a new phone for awhile now I shattered the camera on my G1 and the Nexus one's 530$ price tag and lack of a physical keyboard is a total downer for me. I love my physical keyboard and really hope that these devices persist. I can't stand trying to push the buttons on the screen, i have big hands and always have to correct myself. at the leaked price point Id rather buy a shiny new 42in plasma tv or 3 new monitors for my computer etc, then a phone.
