Here’s an updated overview of the UnNamed ROM for AT&T Galaxy S2 SGH-i77, which is probably the best “stable” ROM for your AT&T Galaxy S2 SGH-i777 right now. There’s a ton of features that come with this ROM including support for 1.6Ghz overclocking, BLN, unlocked USB/wifi tethering, and much more (you can check out full features list in the Credits link at the bottom).
If you have been looking for a great daily driver (until official ICS comes out), try the latest version of UnNamed ROM and let me know how it works for you.
