Here's a nice little hack I found to enable tethering on your iphone without going through the bullcrap that FIDO and ROGERS puts you through. This is really good if you have the $30 500MB data plan as rogers won't allow you to enable tethering. I also hear they may eventually charge after December to even have it enabled on any plan so this is a nice little work around. Click on this link with your iphone and install, then hard reboot and you're rockin! Make sure to click the appropriate carrier, i accept no responsibility for wrong-doing. I wish I had a carpc to tether to via bluetooth for internet on the fly; totally unnessesary but cool nonetheless!
