If you want the cache notifications, you can do as ertyu and Turdle have done and have them sent to your cell phone's e-mail address. You will be incurring data charges, and you don't get the coordinates, just the notification.
With Blackberry, I still get the notifications, but am able to use the built in Web browser to look up the cache page, get a hint, log my find, etc. The cost would be significant, but I am using an unlimited data transfer plan. Even so, that is costing me about 150.00 monthly. I use it mostly for work, so it is worth it for me. Average over the past 3 months has been only about 10 % of my data usage allocated to Geocaching.
Another option is the reliable 3T's network. You can have the e-mail notifications sent to your cell, and give her a call for the cache details. I have used this service in the past and have found it to be quite reasonable, although you may have to put up with some abuse from time to time. ;)
Before I got the Blackberry, and previous to the launch of the 3T's network, I would use my PDA to tap in to an unsecured wireless network. There are tons of them in the city, I don't know about Morris. But when I was in Beausejour, I had not trouble finding a hotspot there.
