So now the users of Samsung galaxy S3 can try out jelly Bean on their S3 but as it is an unofficial ROM it might contain some bugs, and some features might not function properly, So you can use this Rom only to try Jelly bean on your  Galaxy s3 and not for daily uses, so it is better to wait for the official version to be released if you are not a flashaholic.
