Working YouTube and Yahoo!

[maXimus]

I'm not quite sure what is all the difficulty. Here is what I did:

1. I reactivated my phone with the GoPhone plan and original sim to get a working YouTube.
2. I opened YouTube and browsed it to make sure I had working data stored in the phone.
3. I copied the data_ark.plist to my computer using WinSCP (\var\root\Library\Lockdown).
4. I copied the .plist file from activation_records directory to my computer (the name of the file is the number of the sim).
4. I put my other AT&T sim in the phone and did the hack to use other AT&T/Cingular sims in the iPhone (www.hacktheiphone.com).
5. I copied the saved data_ark.plist to the phone (\var\root\Library\Lockdown) and the (sim#).plist file to the activation_records (now there are two, one for each sim).
6. I turned off and restarted the phone.

VOILA!!!! YouTube AND Yahoo!!!

Note:
-I think you must have the original (sim#).plist in the activation_records directory. Maybe the data_ark.plist looks for it. I cannot confirm this because I don't have the binkit loaded and I can't delete it.

what i did was just find the data_ark.plist from a phone that worked, then copied the device certificate data from it and pasted it into the proper location in my data_ark.plist and my sim#.plist file in the activation_records directory and rebooted and it worked just fine at that point.

i didn't try it without this step but I also copied the public and private keys from a phone that is working as well. These files are in the same location as the data_ark.plist file.

In my phone, the public and private keys were the same no matter which sim I activated. That is why I did not bother with them.
