AFAIK they could only really *accuse* you of tethering based on the size of downloads and type of traffic...
Good luck telling anyone at Bell that that 4GB torrent you downloaded was for use on your phone!

On the other hand they could get particularly sneaky... It wouldn't be hard to sniff the TCP/IP traffic coming from your phone and recognize that your useragent ( Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.14) Gecko/20080416 Fedora/2.0.0.14-1.fc8 Firefox/2.0.0.14) doesn't exactly belong to Windows Mobile...

Here is the text of an email I received about a month after signing up for Unlimited Browser :

If you have subscribed to the Unlimited Mobile Browser feature, you can access the Internet on your mobile phone. Please note that it does not include use of your device as a modem to connect to the Internet from your computer. If you plan on using your device as a wireless modem, we suggest that you subscribe to one of our data plans to avoid additional data connectivity charges.

Now that doesn't really mean anything more than *IF* we catch you we *WILL* bill you.... Still not something I am going to bother with...
