I have upgraded twice and downgraded twice to 4.02. Though tethering is not something I use much, both upgrades impaired my ability to do so. It is nice to know that the ability is there and not handicapped. I wonder if this is as a result of using a different Providers version. I had it working both on its own as a stand alone modem or through the VZAccess software. After the upgrades it would not even recognize the BB as a modem, and when I tried using it with the VZAccess software it would simply tell me that it could not connect because it did not have the right user name and password. I even tried using the and it would not work. So the question is, does this happen to anyone else, is it because of the different providers, will this be resolved once Verizon releases it themselves? Any thoughts or ideas would be greatly appreciated. BTW I think that the Sprint Version is a little better than the Telstra.

I'm operating on Bell Mobility's network; officially tethering is not supported with the 7250.

Pre-4.1 I could recognize the BB as a modem and run some diagnostic and initialization tests but I could not launch a connection in any way.

Post-4.1 the initialization tests returned a much more verbose output and I was able to launch a connection and attempt to authenticate on the network. I never did get past the "bad username or password" message here though.

I'll admit that I haven't investigated the differences in depth...

Perhaps the 4.1 OS (Telstra/Sprint/who-ever) returns different output from the BB modem and Verizon's network recognizes your hardware model by ESN and is specifically looking for the authentication data that would be returned by a 4.0 build? (widely speculative, I know ...)

I haven't yet moved from Telstra to Sprint because it does not address the change in the "dial by name" function which is the only thing that I dislike about the Telstra 4.1 build.

Is there anything in particular that makes you prefer the Sprint version?
