Hey if i update my iphone with whatever will allow me to send/receive mms today will it mess up anything? I have a 3G running version 3.0.
If he's talking about the carrier update it shouldn't do anything to your JB. In Canada we received the carrier update months ago, I was on 3.0 JB at the time, I did the update and nothing was changed in regards to the JB. The update is just for certain settings and not the whole OS.
You don't need to have 3.1 for the "official" carrier update. Itunes just "automatically" makes you update to 3.1 before it'll let you automatically update the carrier settings.
I'm here at work and we have 3 iphones. One 3G with a 3.1 Jailbreak, and two 3.0 Jailbreaks (a 3G and a 3Gs). I tried to plug my phone (the 3Gs) in all morning with nothing but the standard "there is a new {3.1} update for your iPhone" message. I took the Jailbroken 3.1 3G and plugged that in and got the carrier update message and updated it's carrier. Then I Plugged in the 3.0 3G and 3Gs and "hold shift and hit update" to manually select the official at&t carrier file that itunes downloaded a second earlier and updated both J/B 3.0's.
So it works for both 3.1 and 3.0, just need to force the carrier update.
im on a mac do u no how 2 do it on a mac

iTunes gives me some kind of error when i try to update the file.
I'm using a 3GS with Firmware 3.0 Jailbroken and iTunes 9.0.
If you have "AT&T Carrier Logo" (or maybe some other carrier logo package?) installed in Cydia, remove it, then reboot, then try again with iTunes. That's what worked for me.
