Correct me if I'm wrong, but does the commcenter get patched when we install ultrasn0w 1.2.5? The reason I ask is I was able to get mms working by installing a .plist override file, but I didn't specifically install any commcenter patch - just ultrasn0w ?

Please help!

I am trying to modify my carrier file but obviously cannot because of the signature that is required. Totally new to this jailbreak thing and don't have a clue how to go about bypassing this.

Can someone please give me an idiots guide?

I'm on iOS5, iPhone 4. Thanks.

PS. Baseband 04.11.08, iOS 5

If your at 4.11, then you are only able to use official carrier anyway - no unlock for that BB, so I'm not sure what you'd be altering a carrier file for?

BUT: there are thousands of detailed threads, blogs and posts about that topic... google one of them, but again, at that BB - your stuck with whatever official carrier that phone was sold through anyway. unless I'm missing something from your question?

Hi toaster, thank you so much for your reply. I see that I did not explain myself properly. I am on an unofficial network called giffgaff which runs off of o2's network. I want to modify the file so that the voicemail button dials 443.

So, are you saying that at my baseband there's no way to do it? I know google is my friend but I am a little confused by all of this and don't really know what I am meant to search for. I know that sounds stupid... Can you offer anymore help?

Are these the instructionss that I am following (found on another thread on this website):

1. Jailbreak your iPhone 4 on the jailbreak website.
2. Open Cydia and install OpenSSH. (Follow the instructions to change your root password!)
3. Download wortel's Patch for Commcenter 4.1 3G/3GS/4G (4.1-4)by wortel (the file listed above
4. Use Cyberduck or another SFTP client to log into your iPhone.
5. In the Directory /System/Library/Frameworks/CoreTelephony.framework/Support, Back up your CommCenter to your PC/Mac in case things go sour.
6. Browse to /var/tmp and upload the file ccp4.1-4_wortel.deb
7. SSH into your iPhone and run the patch by typing:
dpkg -i /var/tmp/ccp4.1-4_wortel.deb
8. Reboot your phone

The thing is, before these instructions was a message to the effect that doing all of this is for experienced hackers only. I don't think I can even describe myself as a "hacker", let alone an experienced one! And I take it that those instructions are for an old patch and that there is no patch for my BB anyway? Will there be?

From iOS 5. onward the file to be patched is CommCenterClassic, CommCenter is still in the system but loaded only if the phone is 4 (CDMA) or 4s. CommCenterClassic Patch for iOS 5-5.0.1 is available from Cydia repo v.backspace.jp/repo.

All you need to do is JB, install CommCenterClassic Patch and modify carrier.plist of the carrier bundle corresponding to your network.

No, Ultrasn0w doesn't modify CommCenter/CommCenterClassic, they are the same before and after installing Ultrasn0w. The override plist works but volatile.

Sorry, but are you saying the patch discussed in the OP has now been released, and can be found at that address?

I have an untethered jailbroken 3GS with new bootrom running 06.15.00, I've unlocked with Ultrasn0w and now run the patch discussed above, still getting no service. Any ideas?
