Reverting to the most up to date, publicly released OS should be step #1, if you're having problems with the phone and/or thinking about asking for a replacement.
I can't imagine that Verizon [or any carrier] would support what is essentially a beta OS...which is exactly what you'd be asking them to do if you asked for a replacement based on the phones performance with .83.
If the phone acts wonky with the most recent Verizon issued OS, then you've got a legitimate claim.
