It's going on a week old soon so I'm wondering if overall you'd do it again or if you prefered the original software the 7520 came with.
FWIW, I'll be using my 7520 with a motorola hs850.
I'm still on the fence here but not as negative as I was before. I'd say in your case it depends solely on how your HS850 is performing now. If you have annoying echo and you want to get rid of it then certainly you should upgrade. If you don't have echo and you feel your HS850 is a bit quiet already then you probably shouldn't. I found my incoming and outgoing volume dropped around 10-20% from a level which I already felt was a bit low.
Not everybody has noticed this though so I can't say if it's just my bad luck or if it's an HS850 issue. I think RIM needs to stop trying to solve this echo issue by hardcoding the setting. Just add a base volume adjustment into the Bluetooth options menu and be done with it.
