I’m going off-topic today to tell you about two really cool iPhone apps you need to check out from my buddy Greg Elliott.

First up is Synchstep, which automagically matches music to your pace, so every step lands to the beat. If you jog to music, this is a sure way to get that life-has-a-soundtrack experience. For now, Synchstep is FREE.

Unfortunately, you need a jailbroken phone (boo Apple!) until the new iPhone comes out over the summer. You can learn about jailbreaking here. If you aren’t comfortable with that stuff, just sign up to get updates for when the iTunes store version is out.

The other app is B-BOT, which Greg did in collaboration with Tristan Eaton of Thunderdog Studios and Peter Cortez (who were part of the national media team that got Barack Obama into the White House). This one lets you make some wicked characters using Tristan’s unique style of art and assign them to your contact list.

As you can see, my B-BOT has a pretty kickass grill. This app works for any iPhone; click here to fire up the iTunes store
