So if you follow this link then apparently this is an unofficial stable release of ICS for the galaxy S2. Also it's been tested by the members of XDA and they also say it's legit.
So if I want to test this out, the link to the download is here, how do you install the rar file? You flash it with Odin right? I loaded some custom roms on my phone a while ago but I can't remember if you flash rar files with Odin or put it on your micro sd and run it from there..(Although I think that you do with zip files.)
Any advice would greatly be appreciated! Thanks!
