If they do offer this service, I see potential for a much-improved version of my great experience with cheap mobile internet access seven years ago.
Back then, a lot of mobile phones didn't offer graphical web-browsing. My phone at the time (some Samsung of some form) was purely text-based, but Telus (in Canada) offered a $2/month unlimited email option.
So, I signed up, and after the novelty of being able to check my email anywhere wore off, I began itching for more information.
Since Telus would still charge me 50 cents for Canada411 lookups, the first thing I did was write an email gateway for canada411.com (which was probably still canada411.sympatico.ca at the time). I had email to my domain set up to go to my home computer, and directed all email to services@mydomain directed through qmail to go to a Perl script.
If the subject was "Canada411" (since Telus allowed me to store various preset subject lines), it would then parse the body as lookup parameters (Last name, First name, City, if I recall correctly). Then it would email me the results in plain text, after doing some web-scraping.
Later on, I added some more "services", like dictionary lookups, recipes, university course schedules, etc. I could even list the current Slashdot headlines if I wanted (in retrospect, since RSS was already around, a basic email-based RSS reader would probably have been more generally-applicable).
Nowadays, with HTML email being the norm for smartphones, you wouldn't even necessarily need to do the web-scraping (which is what ate up most of my development time).
With email-based web-browsing, you can get what you want, but it takes a certain amount of patience and ingenuity.
