Hi I upgraded to IOS 5 yesterday and I went to my voicemail and its giving me an error saying Could not authorize access. I had this error before during one of the 4.x upgrades but I am not sure how I solved it. So far I have tried resetting network settings, reseting my voicemail password and also restoring my phone. The same issue keeps on happening. Even when I go to the phone settings and input my pass code it gives the same error. My phone account still shows having visual voicemail on it and I havent changed anything on my account for a year. Im using a factory unlocked iPhone 4 purchased from Apple Canada and the carrier I'm using is Telus. One thing I did notice which is probably the cause of the issue, is that if press and hold 1 (to dial voicemail) it looks like its calling an AT&T access number instead of Telus Has anyone had this issue or have any ideas on how I can fix it?
