iPhone OS 3.1: Prepping for MMS

AT&T is finally rolling out iPhone MMS support on Friday, September 25, so everyone can start sending their friends pictures in text messages. Preparing for the update is easy and requires almost no effort on your part.

The special carrier update file that's needed to make MMS work on your iPhone should get pushed out late in the morning on Friday. Like other updates, it will be delivered through iTunes, so you'll have to connect your iPhone to your computer before it can be installed.

If iTunes isn't seeing the update, odds are it isn't available yet. You can click the Check for Update button under the Summary tab in iTunes while your iPhone is connected to keep checking for the update.

Once the update is available and installed, you'll be able to start sending pictures in your text messages without even having to restart your iPhone first. AT&T said that iPhone owners won't have to pay extra for MMS service -- it's included in the SMS packages we're already paying for.

The downside to MMS is that first generation iPhone owners can't take advantage of the feature. According to Apple and AT&T, only iPhone 3G and iPhone 3GS users can join in on the fun.
