Just got a SGSIII. Looking for tips, tricks, etc.

So I just upgraded from SGS to SGSIII and wondering what I can do to it. Any recommended roms/kernels? Any tips or tricks that people found out that helps the phone? I remember on the SGS I had to do something in the beginning to fix the GPS. Do people find the GPS to be working well this time around? Anyone know how to get these snes/nes/ emulators working on android? Which ones are the best? I haven't done this but I'm interested in getting some portable old school gaming done on android. Any recommendations of apps to try out in particular for SGSIII? Can it make me breakfast? lol. Thanks guys! Really appreciate any pointers.
