HTC :: Telus Desire No Data In Thunder Bay On Rogers

I have had the Desire (unlocked on Rogers for about 2 weeks and it has worked well in Toronto. I seem to get data from from HSPA, 3G and Edge (get Hs, 3Gs and Es on the notification bar). I arrived yesterday in Thunder Bay and cannot get any data there. I have called Rogers and they have reset the data or whatever they do but no change. I have checked all my APN settings, ensured that I have checked to use mobile connections and done a hard reset of the phone. Nothing works. I not that I have a choice of WCDMA, GSM or auto WCDMA or GSM. I cannot set this on WCDMA without it reverting to the auto position. I suspect that Thunder Bay may have no 3G service and my phone is not dropping to 2G although my experience in Toronto suggests otherwise.

I flew to Kenora tonight and we stopped briefly in Fort Frances where I was able to connect to the Dryden Municpal Telephone System GSM network. The E lit up and it appeared that data was being sent but it didn't get through. This seemed to eliminate the possibility that the radio is simply dead. Incidentally, bluetooth and wifi are working fine as is the voice radio. I have seen it suggested on redflagdeals.com that I need to have the phone rooted to get access to 2G as this was blocked by Telus. I would appreciate anyone's input on this issue. I will be spending 3 or 4 months in Thunder Bay over the next while and need data access. If rooting the phone will do the trick, then I will need to get someone to do it for me as I am a little reluctant to try that myself.
