Got the 520 about a month ago. Like it fine, but there's no Internet Sharing. My previous Nokia 710, a Windows 7.5 phone, had it. Every indication I find on the web is that it should be in the same place - Settings->Internet Sharing. Don't have that option. Has Koodo removed it entirely? I've come across some users of different carriers where it doesn't work due to the carrier blocking it, but haven't seen anyone complain that the option doesn't even exist.
