Today is 25th June 2013 and still there is no news whatsoever about the update for Ace+(seriously doubt if any would ever roll out) , so how long should you wait before you either-
1.)Give it away and buy a premium handset instead so that samsung do care about you(coz you bought a premium handset of theirs)
2.)Throw this handset away or hurl it down a cliff

I think its too late, gingerbread is good but seem from stone age if you compare with daydream
