10. : AT&T chose this week to roll out its MMS (multimedia messaging service) for the iPhone. Although the iPhone debuted two years ago, AT&T's network required updating before it could handle the service, much to the dismay of iPhone owners. Calls for MMS only increased in June after Apple announced that its updated iPhone software could support the service, further pressuring AT&T to prepare its infrastructure. AT&T selected Friday for the service's official launch, but some users have claimed that the company turned on the service earlier this week while others began using the feature a few weeks ago.
