Ok lol i went through this too. IE renames the IPCC file to a .ZIP file. do not unzip it. instead rename the file extension to .IPCC then select it . Itunes will load it just fine

FYI, enabling mms DISABLES tethering.

I tried this and it’s a NO GO… ((sigh))

Has anybody found a way to get around the red exclamation?  I’ve done everything I can and still no luck… I have the 3GS wht32gb and can’t get the red x to go away at all.  Help if you can!

I noticed that my “mms opt out” is still on my account so until that goes away this work around will not work correct?

If you get an error (the red exclamation point) then AT&T hasn’t enabled MMS on your account yet. They won’t have everyone done until the 25th.>

How do you know If you enter the command right?

Reply to this: comment | thread

I can’t get it to work either. I give a error when I try the command on the cmd prompt.

when i try to send a pic i get a RED Exclamation Mark whyy!??? Help???

Reply to this: comment | thread

I made the mistake of commenting on this. so now i keep getting emails. almost all of them are people who are not reading previous posts. AT&T has not give out unlock codes to all phones yet. so it only works on certain phones. not all will work.

Is it just me or is your battery life absolutely horrible since enabling the mms with this hack?

Make sure you download the file with firefox not Internet Explorer. Internet explorer changes the file from a “IPCC” to a zip file.

Reply to this: comment | thread

My safari will not open the IPCC file that I download… WHY?!?!?!

No go in metro ATL. I guess I will have to wait for the rollout next week. Thanks for the info.

Worked like a charm! Thanks so much

I messed up a couple times on enabling the IPCC file thingy.

THE SOLUTION:
In: “C:\Program Files\iTunes\iTunes.exe” /setPrefInt carrier-testing 1 /setPrefInt, the fInt part has no L in it, its an uppercase i (I). So Prefint but with an uppercase i (I).

Works perfect for me btw on my V3.1 iPhone 3GS.

Thanks.

My wife has a 3G, I have a 3GS.  This works on her phone and not mine.  We are on the same account, but not the family share plan.  If we are on the same account, shouldn’t it work for both?

Reply to this: comment | thread

Yeah we’re on 2004 for MMS, buy in everything else we are way beyond any other (as Apple often says: 10 years ahead!) And if his phone has all the good stuff like playing 3D games, Internet browsing, best touch screen tecnology, etc. and/or has a better phone, thne he probably has the iPhone 4GS… :s iPhone Bitch!

I got a syntax error message when copy pasting the command line into the command prompt. But beyond that, the winzip file that downloads isn’t recognizable as an ipsw. I don’t get how that would even work. I have XP and I use safari browser. How can I keep it from downloading the file as a WINZIP file?! How can I make it appear as an ipsw like iTunes needs?

Reply to this: comment | thread

How can you get it to change the file type from winzip to ipcc??

Reply to this: comment | thread

I’m currently using a jailbroken 3GS on 3.0.1 firmware and after locating the .ipcc file and clicking update, the update hangs at “Updating Carrier Settings…” and I’m required to force quit it.

Any ideas on what could be causing this and how I could fix it? Thanks in advance

i got it to work but it only sends pictures out….i cant get any incoming pictures…has anyone had this problem and how did you fix it????

Re-Tested Metro ATL. It is working like a charm!!!

Reply to this: comment | thread

I see a lot of people posting that they can’t see the .ipss file and that iTunes keeps asking for the .ipsw file.

I had this same problem until I did a few things.

First, I’m on Windows XP, using Internet Explorer.
I right clicked on the file and saved it to my desktop.  IE did NOT rename the file as a zip file as people are stating here.  It saved it as an .ipcc file.

Second, make sure your phone is unplugged.  Also, to into task manager and look at the processes that are running.  Anything related to iTunes or iPod, end those processes (and obviously close iTunes).

Then run the command prompt and type in the command noted above.  Note, when typing this, there is no space between the “/ (in the instructions it looks like there is a space there). 

Then, plug in your phone.  Then launch iTunes.

NOW when you shift-click it should give you the option of choosing between the .ipsw and .ipcc file.

ok so i got the update installed and i see all the setting. Got everything working ok up until i try to send a message i get the red exclamation mark.

Called ATT and told them my phone “suddenly” started showing the ability to attach pic’s and contact info but won’t send. They told me there is nothing they can do until friday.

Anyone have any ideas?

Reply to this: comment | thread

When i do it the only file i am able to look up is ipsw and the downloaded file is ipcc. Did I do something wrong?

IF you are getting the issue on a Mac where it does not allow you to select the ipcc file.  Close iTunes and put this in:

defaults write com.apple.iTunes carrier-testing -bool FALSE

then:

defaults write com.apple.iTunes carrier-testing -bool TRUE

now you should be able to select the ipcc and update the carrier. 

I still get red exclamations when sending though…

Be careful if you’re doing this with a jailbroken iPhone 3g. I just tried the method above and it wont’ get past the pineapple.

MMS works but it killed my visual voicemail.  Not a huge problem but I’m not getting any notification that I’ve got any voicemail at all!

Reply to this: comment | thread

I did this hack a few days ago but MMS just started working last night. I’m in Eastlake, OH. My visual voicemail stopped working so I pressed the voicemail button and it started dailing my voicemail, I then pressed * to exit. Then a little screen popped up on my phone asking for my voicemail password, I put that in and now visual voicemail works. Everything is working fine!

This didn’t work for me when I tried it last week, but this morning it suddenly started working!  Cool!

Reply to this: comment | thread

Thanks. File worked perfectly for me on os 3.0 on a 3gs. I had already done the tether activation when I first got the phone so I did nto have to enter any carrier information and it is all working perfectly. No wifi issues or anything…

Worked fine for me on a jailbroken phone.
