Whether you were kinda dying for a S-Off tool for your HTC Rezound or not, now you will — development has just begun for a custom ROM port of Ice Cream Sandwich on HTC’s best device right now.

It’s obvious you gotta have S-Off in bootloader mode to be able to install custom recovery and then flash a custom ROM. So, only those lucky enough to get a Rezound with factory S-Off will be able to install this ROM based on latest OS, Android 4.0, and experience it on what is one of the best screen to grace an android phone, save for Galaxy Nexus which betters it.

It’s pity most of the Rezound phones out there — maybe, more than 98-99%, unless HTC’s security and testing system is flawed — have S-On and thus couldn’t try it, as and when it becomes available. Speaking of which, right now it’s in very alpha version and hasn’t been outed by its developer, IncredibleDoes, who also says it runs and looks good. We don’t doubt it, Rezound’s got a super 1.5GHz dual-core processor and a even gorgeous screen to prove it’s one of the best device to have beautiful Ice Cream Sandwich on.

Those interested can follow the official development thread here for more info, download links (when posted by developer) and get chatty with other users.
