Lifehacker lists: Top 10 Additions to Your Phone’s Contact List. They all look interesting, I particularly want to try out #1.
1. Google SMS (466453)
It’s probably no surprise that Google’s SMS service, which provides a seriously large share of its search functionality via text message, rounds out a list of the most powerful tools you can keep on your phone. Driving directions, metric and currency conversions, local business category results, flight information, and much, much more is offered for free and, at the moment, without ads. You can even set a default location to save yourself a few thumb presses per text. Definitely worth the space in your contact list. (Original post)
