Hello! I used various ROMs on my Galaxy Ace (i changed it from day to day), but all of them had the same problem : No camera, No Gmail Sync,etc... The only one i haven't found a bug in is the MYTH 2 - it's perfect i use it for 2-3 weeks, checked everything, found no problems.. everything works perfectly + very fast, lot of apps have been removed (Google Talk,All Share, etc, i never used them). It worth a try ! I won't change it for a while, it has everything i need
