1. Text GOOGL (46645) a query: weather cmh and it immediately spits back the 3 day forecast! I just did "hometown buffet (stop laughing you snobs) 43202" and am still waiting.
2. Call 800-GOOG-411 for information, e.g., "domino's pizza, cleveland" and you hear the closest eight matches or say "text message" and phone number zapped to you as a text.
3. Text an appointment to GVENT (48368), e.g. 3 pm dentist appt, (don't know how to put in the date, gotta try it) and it's in the calendar.
