Here's two great places to grab free wireless. If you need a wireless device, the best thing to get is a second-hand iPhone. Their batteries last longer than android phones or blackberries and they're the least frustrating to use. Why get a smartphone instead of a small laptop? Because it's easier to just Stan outside and scam their wireless. You just look like you're texting.
Then grab an offline map app, and remember: the iPhone's compass and the offline Toronto maps app can tell you exactly where you are, without any onnection or contract. So don't get a contract. Get wet wipes instead.
