Considering that from last night until today there has been so much information, I think it would be useful to group in this article all the other articles related to jailbreak and decoding. I will tell you that iPhone 4 with baseband 02.x and 03.x cannot be decoded yet and redsn0w 0.9.6 beta 5 does the same jailbreak as version beta 4, the only difference being the possibility to update the baseband in the case of iPhone 3G/3GS .
For the rest of the information, please read the articles below in the order in which they are arranged.
1. Details about the new unlock solution
2. What does the baseband update mean at 06.15.00
3. The unlock solution appeared, what do I do now?
4. Tutorial: Unlock iPhone 3G/3GS using redsn0w 0.9.6 beta 5 and ultrasn0w 1.2 (Windows/Mac)
5. Tutorial: Jailbreak and unlock iPhone 3G/3GS using PwnageTool 4.1.3
6. There could also be an unlock for basebands 05.14.02 and 05.15.04
From what I understand, there is still no PwnageTool that can be used to make a custom ipsw 4.2.1 without having to update the baseband. That's right?
This is the 3rd time I'm asking, if I want to make a custom firmware with ios 4.2.1 without being interested in the new unlock solution, since I have a tel decoded with ultrasnow 1.1-1, will it update my baseband?!?
Not. You will be asked if you want to update.
Zaone. Please explain to me if I use Restore iPhone From Backup - I will have the pictures, the music from the iPhone 3g without restoring to IOS, I mention that I have bb 06.15.00
