Besides talk of course! Seems like there are a lot of things available now.

For example does anyone scan QR Codes with their phones? What is your favorite use?

What about 5 digit short codes? Do you use Google SMS lookup service (sms.google.com)? I just started using short codes for my businesses. On my Celebrating Home website I have a note for updates & specials text "Celebrating" to 90210. I have had several people respond and one order because I offered them a discount for subscribing! I also have started telling people to text "CHSue" to 90210 to get a mobile business card.

Just curious what other moms are doing on their phones besides talking!
