I've submitted patches to the BigBoss Repository now and when they update it, you'll find the Packages "Optus/Virgin GPRS FIX" and "Vodafone AU GPRS FIX" listed under tweaks



Okay so what you need:
* iPhone 2.0 Jailbroken with SSH installed and running on one of the Telstra, Vodafone or Optus(or virgin) as this uses the existing carrierbundles,
* Cyberduck, or some other program that does SFTP (winSCP for windows guys)
Note: I hold no responsibility if anything goes wrong in the process, if worst comes to worst you should be able to restore your carrier.plist to a backup if you create one like I suggest

Step 1: Settings > General > Auto-Lock - Never
Step 2: Open cyberduck and connect to your phone - making sure to choose the SFTP protocol, entering root as the username and the phone's root password (the default is alpine)
Step 2: Click on the address bar (it'll say "/private/var/root") and choose /
Step 3: Browse to /var/mobile/Library/Carrier Bundle.bundle/
Step 4: drag the file called carrier.plist to your desktop, and make a second copy somewhere just in case
Step 5: go to Binary — XML .plist converter - iAppCat and process the carrier.plist file using that page, which will give you another copy of the file in XML format, this will download a converted copy. delete the one on the desktop and make sure the one just downloaded is called carrier.plist, if not rename it so it is.
Step 6: open the newly downloaded carrier.plist in your favourite text editor (my favourite is Smultron) and you should see the following at the top of the file.

Add the following directly underneath
Step 7: Save the carrier.plist, and drag it back into the Carrier Bundle.bundle folder you have in cyberduck
Step 8: Reboot your phone and you should now find a menu called "Cellular Data Network" Under Settings > General > Network

Thanks mate. Worked perfectly for me.

Might be worth pointing out in the guide that if the translation site renames the file (it did for me) you need to change it back before putting it back in your phone.

Updated

How do you install SSH? Without an Installer?

Thanks.

You are a clever fellow Linux_insidev2

BTW the Telstra carrier bundle does give this functionality its Optus & Vodafone that restrict.

Nice hack.

I wonder how you figured out AllowEDGEEditing though as it is not exactly clear from the DTD (http://www.apple.com/DTDs/PropertyList-1.0.dtd). The key and true tags are obvious though (from said DTD).

You need to install it on a jailbroken 2.0 with cydia
By downloading all the carrierbundles from my phone, and reading random ones until I found it, in this case it was found in one of the O2 Carrier bundles :P

I like being able to disable the data, especially when optus like to itemise everything on my bill...

Ingenius!....... But perhaps beyond my current skill set.

Any chance of a baby steps guide ? .... Or something with a pretty GUI. (Joke)
I'd really like to be able to switch this setting. Since upgrading my 1st gen phone to
version 2.0 I've had a couple of accidental data indulgences.... It's a bloody scam to not have this option available.

Try to follow the guide rooread. It seems pretty easy to do. If you run into any issues, post back and I'll try to help once you tell me which step you are stuck at. The steps as given above are pretty straightforward but I am happy to help where you are running into mistakes.

Or, maybe Linux can send you his carrier.plist file already done. If you don't have a jailbroken iPhone already, then that is even more work and there are babysteps for that too, I believe.

Otherwise, I suggest unlockit.co.nz

Thanks mate, I'll give it a crack. Just to be certain though, this WILL work on 1st gen iphone, now running version 2.0 (thanks dev team) with ssh installed right??

I'm tempted to use unlockit.co.nz to disable the data option but would love to have the otion of switching it on occasionly.

Done, great hack

The difficult part for me was establishing the SFTP connection. After that it was a piece of piss.

SFTP may take a while to generate the SSH pair keys for the first time.

And rooread, I don't see why it wouldn't work on a 1st gen.

And if you would like the unlockit.* solution, I'm sure you can have two configs I believe and switch that way which is a bit more annoying though, switching to and from.

Well... probably not. As a general rule, once you need to use SSH or command lines, I reckon it is getting beyond babysteps. You need to be at least toddling! However, I did have a go at writing one once before for something similar. You can find it here. If you put it alongside Linux_insidev2's guide here, it might help you by giving you the babysteps description of some of the actions he describes. Just make sure you don't get them back to front!

Actually, I think you can switch using unlock.co.nz. You could bookmark it and go back to it for the alternative whenever you needed to. I haven't checked to see whether you can download two different profiles from it and switch between them, but it would be worth checking before you start blundering around with SSH if you're not confident with it.

Quoting myself here. But I have now checked and you can download two different profiles, but I can't work out what you then do with them. In General settings, a new item appears just before the Reset iten, called Profiles, and it shows that there are two loaded. But there doesn't seem to be any way to switch back and forwards between them. Does anyone know how the Profiles things is supposed to work and what it is supposed to do?

This works great

there are lots of options in the carrier.plist file..

like Visual Voicemail etc
