There are more than three dev's. Just not all of us cook for public consumption. My cup of tea is finding wasted space, incorrectly formatted drivers & configuration files & optimizing files for the best experience. I send ideas as well as files to several devs along with guidance on things most chefs include needlessly in roms.
For ICS to work (we have limited access to an ICS Vivid) the bootloader needs to be updated. This means waiting for HTC/AT&T to release the update, or getting back on the road to S-Off. S-Off has been acheived on a few test devices, but it not an easily implemented process at this point & it requires some paid development software & working knowledge of SQL, SPL, IDA, an Arn Cross Compiler as well as knowledge of firmware & radio modding. JCase may be helpful in acheiving S-Off on the Holiday as so far I haven't heard back from the dev with the ICS Vivid that I gave some special extraction directions to.
Worse comes to worse, I may just pick u where this rom left off. In the mean time, I am working on a couple driver projects as well as rehashing the S-Off initiative.
