Though I feel for her situation, as upgrades to a particular service are performed, older hardware can become incompatible (common knowledge). Waiting up to 3 days for a new modem could be much worse. If she's concerned about getting it setup, get a Mac-savvy Bell tech to set it up for her (believe it or not, there are a few), or hire a Mac tech to do it for her.
A single piece of hardware isn't going to last forever, and if her modem needs replacing, it needs replacing if that's what it takes to stay connected to upgraded Sympatico/Bell services. (unless I'm reading something incorrectly in your post.)
