Although most of my friends are using 3G/s now, I do get the odd 2G phone to play with.

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:

Install 3.1.2
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 2 x 2g iPhones!

Had a client over today with some Mac issues.
Was getting disk full messages, despite having 130Gig free.

Did the usual stuff – disk repair, disk verify (caught some small things).
That fixed the disk full messages.

Then the client told me – oh, by the way, Safari doesn’t open.

Tailing the system log in console still revealed issues.

14/04/09 09:07:43 com.apple.launchctl.System[2] could not fetch history: Cannot allocate memory
14/04/09 09:07:43 com.apple.launchctl.System[2] BootCacheControl: could not stop cache/fetch history: Cannot allocate memory

A quick google of that error showed it was caused by…. Wacom drivers.

While Wacom have updated drivers for other tablets, the client uses a Bamboo, which hasn’t had driver updates since 2007.

Checking the logs while opening Safari revealed that it was trying to open a non-existent file called com.pentablet.defaults.xml

On the off chance that this would work, I created a blank file in terminal.

Terminal
sudo su
[enter in your password]
cd /Library/Preferences
ls -al com.pentablet.defaults.xml

If (and ONLY if) no file is found, do this:

echo > com.pentablet.defaults.xml
exit
exit

Safari will open again.

Hopefully Wacom will release newer less buggy drivers sometime soon.

One of my clients called asking why all his image attachments were suddenly postage stamp sized.
We both use Mac’s, and to be honest I had no idea, until I tried to send an image attachment myself.

Turns out that in Apple Mail, the simple stuff eludes us “smart” IT types by being obscure.

After attaching an image in Mail, Apple sneaks a new menu at the bottom of the page where you can choose the image size.

See below for an example:

Once we had that changed back to a more reasonable default (Medium in this case), all was well in the land, and we both learned something new!

Notes for Apple (just in case someone’s listening):

I like the idea, but I think the implementation leaves something to be desired.  The UI for this is very non-intuitive, some kind of hinting wouldn’t go amiss here, or dare I say it, a total relocation of this to the top of the window with the other icons and menu options.
