Just saw a commercial for them on TV, apparently you can text any question you want answered to 542542, and it will get answered,
for a price.The carriers supporting this service on 542542 include: Alltel, AT&T, Cellular One, Cellular South, Cincinnati Bell, Cricket, N-Telus, Cellcom, Sprint-Nextel, Boost, T-Mobile, US Cellular, Verizon Wireless & Virgin Mobile. The price is 99 cents for all carriers.
Sounds pretty good for people on the go who don't have access to the internet.
You can visit their website
here for more info. You can even apply to become an "agent", if you meet the requirements.
It may cost a buck, but I'm actually thinking of using it in a pinch... :o
