MMS is finally coming to the iPhone in a few hours under the form of a carrier update. As usual when there is something to update on your iPhone, it is legitimate to wonder whether it will mess it up or not.
If you’re on a stock iPhone, then there is nothing to worry about. However, it can be a little tricky if your iPhone is jailbroken and you want to keep the jailbreak.
Some jailbreakers are concerned that they will have to update to 3.1 in order to install the MMS carrier update. I can’t be 100% sure until it’s actually out but I’m very confident you won’t have to update to OS 3.1 to have MMS.
The MMS capability was introduced with OS 3.0 and iPhone users in many countries have enjoyed MMS since then because their carrier allowed them to, not because they were on 3.1. In other words, you most likely won’t have to update to 3.1 to download and install the carrier update.
Now there is always a risk that Apple asked AT&T to make it so you have to be on 3.1 to download the carrier update but I really doubt it.
The biggest risk is actually you! Yes, you are the biggest threat to your jailbreak. When you plug in this iPhone in iTunes tomorrow, a message will probably pop up saying that there is a newer firmware and asking if you want to update. Don’t!
The carrier update should be a separate pop up. This is the one that you may agree to.
But hey, what do I know? These are just my thoughts and I might be way off so please follow my advice at your own risks. Something tells me you will be able to get MMS through this AT&T carrier update without losing your jailbreak though.
