O2 box IV on Be* Unlimited

I bought my own O2 box IV when that special deal was going on, will this box work on the Be* network as well as O2?

Reason is, I want to sell the box as I may be leaving O2 very soon. Anyone know if it works on both networks please?

Umm yes it should work on BE fine enough.

Thanks for that advice, this box has been very reliable for me and I am in the process of leaving O2 and going to Be Unlimited. I just hope I am not making a mistake.
