Well I took the plunge and updated to the GM of iPhone OS 3.0. Once updated the iPhone booted up and sat on activating for ages……………
Eventually it activated. Shortly after activating I got a text from o2 saying :-
MMS is now setup for you. We will let you know when it is setup and ready to use.
About an hour later I got a MMS from O2 saying its all setup and ready to use. As you can see below, sends and receives fine.
At last the iPhone now has MMS and joins every other phone in having it.

I recently took the plunge and installed the beta version of iPhone OS 3.0.
I found that my battery life took a MASSIVE hit. It was depleted within around 8 hours.
So I downgraded back to 2.2.1 but it didn’t role back the baseband. Battery life was still bad.
I found out about an app called Fuzzy Baseband Downgrader in Cydia.
Once i had jailbreaked my phone I downloaded it in cydia.
Now all is good and battery life back to normal.
I jumped the gun when 2.2.1 came out and upgraded. I then found out that you could no longer unlock the iPhone to any network using yellowsn0w.
Yesterday though I found a nifty tool which you can use to downgrade your iPhone 3G to an older Baseband allowing unlock again.
I have compilied all the information together that I have read and made hopefully an easy tutorial to follow below.
