Let's say that you're hanging out in your office one day when all of a sudden you spy one of your oldest friends.

After a passionate kiss, you decide to exchange contact information, but you don't have any business cards.

Whatever shall you do? Don't fear, Bump is here for iPhones! Bump is a quick, easy way to share contact information with any other iPhone user with the Bump app installed. It's free, so download it, install it, and you're ready to go.

Step 1: Open Bump and either create your profile or select an existing one. Save your settings and wait for a friend to show up so you can Bump them!

Step 2: When you meet someone to Bump, just open the Bump app on your iPhone:

Step 3: Wait for the app to notify you that it's ready, then Bump with your friend:

Step 4: Confirm the transfer, and now your friend's profile is saved in your Contacts. It's that easy!

If you're going to BlogHer in four days, and you have an iPhone or iPod Touch, I want to Bump you until you're sore. Be ready.
