Erev Rosh Hashanah is a time for prayer, introspection, teshuvah, and...text messaging? Apparently so. Last year on the day before Rosh Hashanah, Israeli cell phone users sent 18 million text messages. That's twice the usual average of 9 million texts a day in a country of 7 million people.

Rosh Hashanah greetings aren't the only messages passing through Israeli mobile phones. Prayers are too. Thanks to Israeli company SMS2Wall, cell users all over the world can text a prayer to the Kotel (Western Wall). They just compose a text message-"WALL" (space) then the prayer-and send it to the number 46898. SMS2Wall prints out the prayers once a week, folds them in a way that will maintain the writers' privacy, and places them in cracks of the Kotel, all for only 99 cents per message.
