Today I had another crack at enabling MMS on a 2G. For some reason not much documentation, and too much misinformation out there on the net.

Guaranteed working instructions for China Mobile users below:

Note #1 – this is for 2G iPhones only. 3G and newer phones, skip to the MMS settings at the bottom of the post, and put those in Settings / General / Network / Cellular Data Network…

Note #2 – 2G users – if you used BlackRa1n to jailbreak, this will not work either, and will b0rk wireless. Use PwnageTool, and create a 3.1.3 jailbroken / boot neutered (carrier unlock) firmware, install that first, then continue.

iPhone 2G users –

Install 3.1.3
Jailbreak with usual steps.
Add cydia.ifoneguide.nl in Cydia / Sources
Wait a bazillion years for cydia to timeout with the various blocked in China repositories.
Click Search
Download Activate 2G MMS
Reboot

Normally we’d be done, however the MMS settings won’t let us save a diffferent MMS and GPRS name, so we need to install a specific IPCC (iPhone Carrier Setting file) for China Telecom.
As China Telecom is (at time of writing) not an official iPhone supplier, they don’t have an IPCC file, so we need to roll our own.

Here’s one I found earlier – ChinaMobileCarrierSettingsWithMMS.zip

Download that, unzip, and throw on the desktop.

We’ll need to tell iTunes that its ok to use the IPCC file first, so close iTunes.
Now head off to terminal (or a DOS window for those on Windows), then paste this in.

Mac users:
defaults write com.apple.iTunes carrier-testing -bool TRUE

Windows users:
(32 bit)
“C:\Program Files\iTunes\iTunes.exe” /setPrefInt carrier-testing 1

(64 bit)
“C:\Program Files (x86)\iTunes\iTunes.exe” /setPrefInt carrier-testing 1

Done?

Ok, now open iTunes again, connect the phone if its not connected, and..

Mac Users:

Press + hold down Alt(option), and Click “Update”

Windows Users:

Press + hold down shift, then Click “Update”

iTunes will prompt you for a file.
Choose the IPCC file you downloaded.

Sync the phone.

Finally… shut the phone off again.

Once you power up again, you should be able to send/ receive MMS!

If its not working for you, check that the settings are in there –

Settings / General / Network / Cellular Data Network

(anything not listed below should be empty)

Cellular Data
APN -> cmnet

MMS
APN -> cmwap
MMSC -> http://mmsc.monternet.com
MMS Proxy -> 10.0.0.172
MMS Max Message Size -> 300172

Tested, and working on lots of 2g iPhones.

Useful if you want to rejig the QoS settings.

The other standard modem HG520S is easier – admin / admin

Might be useful for some folks. I’m mostly posting here for myself, as I’ll probably forget and need to google it later.

Shanghai Telecoms official response below:

武胜机房托管了服务器61.129.88段在4月16日12:00-14:00出现无法访问连接，经检查该段均出现该种情况。我们公司技术向电信反映该情况后，经电信查看是由于该段中有主机发送广播包导致路由中毒（环路）而造成的，经过紧急的抢修最终恢复正常。此次给贵公司的日常运作带来很多不便，在此深表歉意。

Unfortunately once they had resolved their router issues, at around 3pm,  Shanghai Telecom decided to create some new ones, by arbitrarily rebooting all the servers in that address space.
Due to their actions, on reboot, our database server could not fully mount the data partition, and so a number of our client websites were unaccessible, as was our webmail service.

Repairing the damage caused by Shanghai Telecoms actions took around 2 1/2 hours.

Full services resumed at approximately 5:20pm

All services are currently running smoothly, although we do have some reports of connectivity issues from some clients.
If you are still unable to connect to the mail server, please turn off your ADSL modem or Router, and log onto the internet again.
(This will clear any route issues  in your router, and you should be able to connect successfully.)

Apologies for the inconvenience.

Lawrence.
