Just a heads up, there is a beta available based off Virgin ICS leak already. I am currently running it. A few things to note:
1) check the build.prop and there are a few edits that can be made
2) chinese market is included, not google play but that is fixable by swapping supermarket.apk with vending.apk from Mobstersgunz Miui build(system/app before flashing)
3) i have swapped out the apns.xml out of framework-res.apk but have not verified if mms is working
4) On first boot you will see chinese characters in notification drop down and on lock screen but after first reboot it is all in english
5) When an app requests root Permission Manager FC's(workaround is to select ok, push home, open permission manager, select manage ROOT permission, select the app, select allow and ok)
6) MMS does not work with stock app (about to try go sms)
7)3D gallery works
I will continue to post my findings here, but I ran the previous version for awhile with no problems. Since it is based off Sense, almost everything already works. There is not a way to turn on 4G that I can find, but I am sure it would work as well. I am currently running with Anthrax 2.8a.
