“To enable Tethering on this account, contact carrier”

[atekant]

- I just updated my early July 3GS to 3.1.2 with pwnage (keeping old bb).
- activated on official carrier
- Unlocked it with ultrasn0w
- completed the tethering hack (commcenter patch)
- tried it as a new phone and a restore

Now, other than the official carrier (which allows it), tethering won't work.
- I downloaded the ipcc files from benm.at and unlockit.nz
- I tried it with UK O2, Italy Wind, and AT&T

Instead of seeing a tethering toggle like I did on 3.0, now I see a button to "enable tethering"
When I click that button, I get the message in the title (or some variation of it) on each carrier, other than the official (which allows tethering, and still shows the toggle).

Unfortunately Googling didn't return anything useful that I can see.

Anyone know how to get around this?

thanks

I was getting that and I wasn't able to get it to work due to having, i beleive, previous profiles and not the bb 5.11.07.
Once i got that i had to restore and start over

I had no profiles at all when I tried it the first time, and made sure to remove profiles between tests. Did you mean it worked with 5.11.07?

I've seen that message before. Make sure your internet works on your phone to begin with, and if that works, mayby your carrier is using a different APN for tethering, and you need to contact them to enable your tethering.

One thing you can do is get the latest IPCC for your Carrier, and edit it yourself, or SFTP into your phone and go into /System/Library/Carrier Bundles and copy your carrier bundle to your computer. Create a folder called Payload, and put it in there.
Edit the carrier.plist inside the bundle. I opened Fido's in Canada just to see it...

Notice the typemasks?
Here is the key to typemasks:


First thing I would do, it remove the signatures, because they wont work anyways because they change with any modification of the typemask. Then notice the typemask 48 that is the APN isp.fido.apn? What I would do is remove that APN entirely. See the typemask of 7, I would change that to 55. Then there is the other one that is 6, but is the same APN. I don't understand that one, but I would leave it alone. But you can delete it and everything would still work for them.

So now I am left with

	<key>apns</key>
	<array>
		<dict>
			<key>apn</key>
			<string>fido-core-appl1.apn</string>
			<key>password</key>
			<string></string>
			<key>type-mask</key>
			<integer>7</integer>
			<key>username</key>
			<string></string>
		</dict>
		<dict>
			<key>apn</key>
			<string>fido-core-appl1.apn</string>
			<key>password</key>
			<string></string>
			<key>type-mask</key>
			<integer>6</integer>
			<key>username</key>
			<string></string>
		</dict>
	</array>

Save it. Then Go to the folder with Payloads in it.
If you are on a MAC, right click it, and compress it. on a pc, just make a zip of it. Then rename it to (Your Carrier).ipcc, and load on your phone with itunes.

Or you can just replace the carrier.plist in the bundle on your phone.. But if you have to restore your phone, then you will have to do it all over again, instead of just installing your new IPCC file you made.

jaminmc, thanks for the detailed instructions.
Although my problem is opposite, it gave me some ideas I might try.
I *do* have tethering support with my official carrier, and it works without issues.
The problem appears when I try other SIMs I have like O2, and Wind Italy.
I have been using mobileconfig files, rather than IPCC files, but the master IPCC might be taking precedence somehow when it comes to tethering APNs, I will try the ipcc method.

Also, obviously I did not travel to UK and Italy to try out if the SIMs worked after jb/unlock, so it is also possible that the Fido settings are still being used somehow because I am on their network, and the error could be that the travelling O2 card does not have tethering allowed.

I will try things.

Mobileconfig files?? I stopeed using those a long time ago. As far as I know, Carriers don't use them, and only the jailbreak community does.... I think they are sloppy, and could be the cause of problems. The IPCC method is what Carriers use, so just modify them, and you are bound to be more compatable. Also, I think that with the mobile config files, they don't play well when you have more than one.. At least that was my experience when I was messing with T-mobile and AT&T configs.

I even made a good T-mobile IPCC from scratch... Well, mostly. Used T-mobile from Germany as a template, and changed all the settings, and researched the accepeted SIM provider numbers. So, I put in a T-Mobile SIM, and Data works, and it even has a fancy T-Mobile Logo.

Here is my ATT_US.ipcc, and Here is my T-Mobile_US.ipcc For anyone who may want to try them
