Before upgrading my sons phone (8100 on ATT) he was unable to send MMS using our Family Unlimited Text and Multimedia plan. He can now send MMS messages to a phone or e-mail address. I didn't see if this was already discussed, but I thought it was worth mentioning. He has no BB data plan.

He also has use of the Medianet Browser, which he did not have before and can send and receive MMS. He could not receive pictures on his phone prior to this upgrade. He still prefers texting.
