You’ve been waiting for it. We’ve been bitching about it, but it’s here! MMS for iPhone is available for download from iTunes as a “carrier update”.

Open iTunes, plug your iPhone in and you should have a message saying that a carrier update is available for download.

As I wrote yesterday, I don’t think this carrier update can mess up your jailbreak but it might kill your tethering hack if you activated it.

Now the big question is whether AT&T’s network will be strong enough to handle all these MMS that are going to be sent.

Personally, I couldn’t care less about MMS but I know many of you are anxious to send and receive picture messages.

Are you excited?

Update: It seems you have to be on OS 3.1 to be able to download the carrier update. Yet another sneaky move from Apple. Oh well…
