When you’re lost and out of mobile internet territory, that’s when directions are probably a really helpful thing. If you can still eke out an SMS message, you can text GOOGLE with a message formatted as "Directions A to B," substituting a town, ZIP code, or street address for A and B. Google will hit you back with the same directions it would provide via Maps, and your friends will say that you’ve saved this road trip. (thx Lifehacker)
