HOWTO: Unlock/Setup AT&T Blue (Charter Plan) Subscribers
Since there doesn't seem to be a single dedicated thread/resource for those of us who are long-time AT&T subscribers back when it was AT&T Wireless the first time. ;)
To be clear -- this is for people like me who are "AT&T Blue" customers with our legacy charter plans or similar.
The following is what I did to get up and running, and I can at least confirm i
I take no credit for coming up with any of this...it's almost entirely from searching on this and other forums.
The steps are roughly:
Jailbreak your iPhone
Modify EDGE settings
Jailbreak your virgin iPhone:
Lots of resources here. You can use the documentation at www.hacktheiphone.com as a great reference.
I prefer to just install Installer.app -- it will jailbreak the iPhone as part of its installation process automatically. You can get Installer.app at iphone.nullriver.com/beta/.
It's worth noting that I do not recommend activating the iPhone at this stage quite yet.
Your next step is to unlock YouTube using the PACAY script and files.
There are two methods that I know of to get YouTube going. One involves editing the activation records on the iPhone to mimic a known legitimate phone on the network. This method is potentially problematic as there are already many people out there at this point that are using the same activation records...at some point should AT&T choose to wise up, they could suddenly find themselves inactive.
The second method, and the one that I use, involves patching the lockdownd binary to make it think it always has the valid activation records its looking for. Essentially, whenever it does a "validity check" it will return a good result. This will serve a dual purpose -- YouTube functionality will be enabled on your iPhone and, more importantly, you can swtich SIMs later without having to reactivate your phone every time.
Search this forum for the PACAY script...I won't link to it here.
Unlock your iPhone
I paid for my unlock with IPSF, but I've also unlocked an iPhone with the free solution as well...the free unlock solution can be had at iphone.unlock.no.
By the end of this stage you should have a fully unlocked iPhone and you should be able to make and receive phone calls as well as text messages (SMS) without a problem.
This was borrowed from another thread on this forum --
Presumably you know how to get files on and off your iPhone. If you do not, please see www.hacktheiphone.com and look for the section on how to get files on and off using WinSCP or ssh.
As AT&T Blue customers we have an inherent problem -- our EDGE settings are different than the Cingular/newAT&T folks, but the iPhone doesn't know this nor care. If you put in a non-AT&T SIM in the iPhone a menu option for EDGE settings can be found under the Settings application. However, since it thinks we're AT&T and it already knows what those settings should be, it won't display the application. Which leaves us to editing them manually...
The file you are looking for is:
Find the following section:
You will need to alter the apn string to proxy and remove the password. You should be left with the following:
There is another APN section in that file -- it is safe to ignore it for our purposes, so do not modify it.
Once you've modified the file and gotten it back on the iPhone (or edited it in-place on the iPhone if you know how), you will need to restart your iPhone by holding down the on/off button until prompted to slide to turn off.
Once your iPhone has been restarted, you should have a working EDGE connection.
That's it...pretty straightforward. Enjoy.
ATT Customer with older plan
I was wondering if anyone can confirm this....
I already have an iphone, and I am on an old ATT plan, that I unlocked the phone with, and am using with no issues.
My wife now wants one, and she too is on ATT but on the newer sim, the orange kind, out of contract,
If i want to get hers to work, do I still have to unlock the phone, or can I get away with jailbreak and acgtivation without having to unlock the phone seeing as an ATT Sim card will be used.
I tried searching the site on this but was unable to find anything, so I apologize in advance if there is answers to this in the forum.....I just could not find it.
Please let me know,
