I am using an Ipad3 with IOS6.0.1
But guess what, the problem seems to be resolved, I just checked just to find it working. It looks like we had a quoting problem in one of our scripts, and once we fixed this, the search worked as well.
So this one was on my side I suppose.
Thanks for looking into this.
Do you have an estimate on when your 2.0 will be officially released?
