I currently have a 928 running 8.1 and I just found out Verizon is running a special where I can switch to an Edge plan before my contract is up and I've been thinking of taking them up on that to get an Icon. If I were to do that however I'd have to trade the 928 in "in working condition". It's in working condition but I'm wondering if the fact that it's running the dev preview would screw things up with my eligibility. I feel like it's likely they won't even notice (especially at my store, they're usually completely dense) but on the chance they do, do you think it would be a good idea to flash it back to 8 beforehand? I'm going to have to factory reset it anyway, but that I can do in the store while reflashing I'd have to do at home.
