I think, like other Samsung devices, if you keep entering it should give you the option of the backup pin, or your Gmail address and password.

Yes, you don't need to reset your device with Google's Android Device Manager, just locate it, then choose Lock where you can enter a new pin code which will override the old lock.

@B.Diddy - I have been losing confidence in ADM and not sure if it finds wifi only tablets (this may be 3g).
Also it now won't locate my 2 phones if location is off, where I'm sure it always did before.
