We have a customer that is currently running 4612's and 4624's primarily on an IPO v6.0(1084), even though documentation says they're not technically supposed to work on 3.1+. Anyone know if they'll still work on an 8.0/8.1 FP1 system? 75% or more of their phones are these models, out of 85 sets.

Long story short we took over this account and were looking to upgrade them and found out that they were sold a demo kit unbeknownst to them.
