The recently released iPhone 3.1.2 update also includes a carrier update for AT&T iPhone 3G and iPhone 3GS users. The carrier is updated to AT&T 5.6. The baseband/modem firmware for the iPhone 3.1.2 update still remains at 05.11.07 (which currenty cannot be unlocked).

How to update iPhone 3.1.2 carrier settings

1. Download and install the iPhone 3.1.2 firmware to your iPhone 3G or iPhone 3GS.

2. Once the iPhone  3.1.2 firmware is installed, iTunes will display a message saying: “An update to the carrier settings for your iPhone is available. Would you like to download it now?“. Click Download and Update.

3. Once you’ve clicked the download and update button, iTunes will automatically update your carrier settings and display the following message: “Your iPhone carrier settings were updated successfully“. That’s it, you’re done!

I’m not sure what is included in these new carrier settings. Last time Apple issued the carrier settings to enable MMS on AT&T, maybe these carrier settings will enable VoIP over 3G, now that AT&T is allowing Skype to use 3G. What do you think?

Today Apple released the iPhone 3.1.2 update for iPhone, iPhone 3G, iPhone 3GS, and iPod Touch users. Some users are having difficulty downloading the update through iTunes. If you’re one of these users, you can download the iPhone 3.1.2 firmware directly using the links below. Just download and then restore through iTunes

Remember, if you have a jailbreak or unlock you will loose it right now.

Almost a month ago, Apple released the iPhone 3.1 update. Today Apple has released the iPhone 3.1.2 update for iPhone and iPod Touch users. This update does not really add anything new, but it does fix important bugs so iPhone and iPod Touch users should update.

iPhone 3.1.2 Jailbreaking information

Today AT&T released the iPhone MMS Update for iPhone 3G and iPhone 3GS users. Is iPhone MMS not working for you? I’ve read comments where people have been saying that MMS is not working for them. I just tried the MMS update on my iPhone 3GS running on iPhone 3.0.1 firmware and the MMS update worked fine for me.

If you have iPhone 3.1 firmware, then follow the enable iPhone 3G/iPhone 3GS MMS update through iTunes guide. If you have iPhone 3.0 or iPhone 3.0.1 firmware then follow the enable MMS on iPhone 3.0 or iPhone 3.0.1 guide.

Feel free to share any MMS problems that you have in the comments below! If you can’t get it to work, you may want to try again later. The most common thing that most people are forgetting to do is reboot! Remember to reboot your iPhone after applying the MMS update and it should work for you.

A lot of iPhone 3G and iPhone 3GS users are still using firmware 3.0, due to the fact that a Windows jailbreak has not been released for iPhone 3.1 firmware.  AT&T released MMS for the iPhone today, and many jailbroken iPhone 3G/iPhone 3GS users still want MMS on their iPhones but don’t want to update to 3.1 until there is a jailbreak released for it. Thankfully this can be done! I’ve added the AT&T 5.5 carrier profile download which AT&T released today. Follow my guide below to learn how to add it to your iPhone 3G or iPhone 3GS.

Note: If you are on iPhone 3.1 firmware, follow my Enable iPhone 3G/iPhone 3GS MMS update through iTunes instead.

Enable MMS on AT&T iPhone 3G/3GS 3.0 or 3.0.1 using Mac

1. If you have iTunes open, then right-click and click Quit to close iTunes.

2. Go to Applications -> Utilities and open the Terminal application.

3. Copy and paste the following command in to Terminal: defaults write com.apple.iTunes carrier-testing -bool TRUE

4. Press Return on your keyboard.

5. Download IPCC file (this IPCC File is the latest 5.5 file that AT&T released in iTunes today, right click this link and save it as ATT_US.ipcc).

6. Connect your iPhone 3G/iPhone 3GS to your computer and open iTunes.

7. Press Option on your keyboard and at the same time click on Update in the iTunes window.

8. Locate your ATT_US.ipcc file you downloaded in step 5 and click Choose.

9. Time to reboot your iPhone. Hold down the top button of your iPhone until the “slide to turn off” message appears, slide and turn your iPhone off. Turn your iPhone on again and it should have MMS on it!

Today iPhone users in USA will finally get MMS! AT&T will issue a carrier update through iTunes 9.0.1. In this post I will show you how you can get the MMS update on your iPhone 3G or iPhone 3GS once it’s out.

This is not a firmware update, it’s a carrier update so you will be able to download and enable MMS quickly on your iPhone 3G or iPhone 3GS.

How to enable MMS through iTunes

1. Download iTunes 9.0.1 (if you don’t already have it).

2. Connect your iPhone 3G or iPhone 3GS to your computer and open iTunes.

3. Once the iPhone MMS update is available, you will see the following message on iTunes: “An update to the carrier settings for your iPhone is available. Would you like to install it now?“. Click “Update Settings“.

4. After you click “Update Settings“, iTunes will show the following message: “Your iPhone carrier settings were updated successfully“. Click “Ok“.

5. Reboot your iPhone 3G or iPhone 3GS. Hold down your power button until the Slide to Power off button appears, slide to power off. When your iPhone is off, press the power button to turn it on again.

You should now have MMS on your iPhone 3G or iPhone 3GS!

Note: This won’t work on the iPhone 2G.

AT&T is about to release the iPhone MMS Update for iPhone 3G and iPhone 3GS users. iPhone Picture Messaging and video messaging will soon be available to iPhone users.

Many people seem to be excited about this update. iPhone users have been waiting for MMS since the launch of iPhone OS 3.0, and it’s about time AT&T releases it. I got a chance to try iPhone Picture messaging early by using an enable iPhone MMS hack. Sending an MMS picture message through the iPhone 3G was pretty easy, but it took some time for it to get sent! I don’t have an iPhone 3GS so I was not able to test video messaging.

MMS on AT&T’s network seems to work fine right now. I hope it doesn’t slow down after AT&T’s update! I’ll be testing MMS after AT&T officially releases it to see if it will still work at the same speed. I’m expecting AT&T’s network to go down! Many people will be using it.

The AT&T iPhone MMS Update is still coming today, as AT&T promised us. Our inbox has been flooding with a lot of questions about this update, and how it works. We’ve already answered most of the questions in our posts.

iPhone MMS Update FAQ

1. What is MMS? MMS is basically picture or video messaging.

2. Is MMS Free? Yes it’s 100% free! You won’t get charged for sending any picture or video messages on AT&T.

3. How do I get the iPhone MMS Update? Make sure you download iTunes 9.0.1, and make sure you’re updated to iPhone 3.1 firmware as well. Apple will issue an update through iTunes which will update your carrier settings and allow you to use MMS.

4. When will iPhone MMS be out? It will be out today, some time very soon! AT&T promised it would be at late Pacific time.

5. Does iPhone MMS work on iPhone 2G? No it only works on iPhone 3G and iPhone 3GS.

Stay tuned, we’ll post a guide here once AT&T officially releases their iPhone MMS update.

AT&T promised that they will bring iPhone MMS to the iPhone 3G and iPhone 3GS today. They have not announced any specific time, but they have said that it will be at late morning, Pacific time.

Many people are looking forward to the launch of MMS. I’ve searched on Twitter and there are a lot of tweets that people are posting about iPhone MMS. It’s amazing how so many people are looking forward to this service. Of course, MMS is FREE.

To prepare for the iPhone MMS update, download iTunes 9.0.1 and make sure your iPhone 3G or iPhone 3GS is using iPhone 3.1 firmware. The iPhone 2G or 1 G will not get an MMS update! If you still cannot wait for AT&T to release the update, you can enable MMS on iPhone 3G/iPhone 3GS 3.1 with a hack, but it may or may not work.  Do you think AT&T will be able to handle the iPhone MMS traffic today? Will you be using MMS a lot on your iPhone? Let us know in the comments.

Tomorrow AT&T will be releasing Picture/Video messaging aka MMS to iPhone 3G and iPhone 3GS users. According to AT&T’s Facebook page, MMS will be enabled on late morning, Pacific time, on Friday.

AT&T will be issuing a carrier update through iTunes (not a firmware update) in order to enable MMS. A carrier update file will only be a few kilobytes so it won’t take long for iPhone users to add MMS functionality. Many of our readers have been lucky enough to already enable MMS on AT&T iPhone 3G/3GS 3.1 using a guide I posted a couple of days ago.

Millions of users are expected to be using MMS on their iPhone tomorrow. While many AT&T users are excited about MMS, there are some users who are not excited about this for fear of AT&T’s network slowing or possibly going down. Will AT&T be able to handle all the MMS traffic, or will they go down? Let us know how you feel about MMS coming to the iPhone tomorrow, and whether or not you think AT&T will be able to handle all the traffic.
