A couple months ago I bought a Samsung Gravity Touch on a 3 year contract from Bell ($30/mo). The handset was $49.99 CAD. Now, I'm not sure if the phone itself is going to last until 2013 without breaking. If it does break, can I buy another handset for $50 and continue with the same plan, without restarting? (Or, if they've stopped selling the Samsung Gravity T by then, can I buy another handset?)
