Yes but be careful. I updated mine to v3 and there are two major problems that have totally idled by units as a result:
1) dual mining (sha256 + scrypt) is gone, it is 100% scrypt now
2) they v3 firmware seems to be very picky about which pools it works with. I can tell you that multipool.us and wemineall.com do NOT WORK. I need to find a new pool to test it but for now I am down.
Actually it's the other way around, some pools are just really picky, for example they mark perfectly valid shares as invalid, or just time out the stratum for no reason at all.
