Greetings from New Zealand!!
I was hoping someone may be kind enough to shed some light on my situation, I have been searching "Everywhere" for the last 3 hours and am still unable to find some specific's related to my goal and situation.
Firstly, I have just purchased a second hand iPhone 3GS running iOS4.0 and it seems to be activated but not unlocked so its basically an iPod Touch at present.
I am going crazy waiting for the new Jailbreak tool so I decided to investigate whether I could downgrade to an earlier Firmware.
I used TinyUmbrella and found that SHSH's exist for my phone on Sauriks server for firmware 3.1.3 so I have downloaded them to my PC.
Phone Details
Firmware: 4.0
Model: MC135LL
Baseband: 05.13.04
Bootloader: 6.4 (new iboot)
My issue and question relates to the Jailbreaking and Hacktivation of my phone. I believe my phone is locked to the AT&T network.
I believe downgrading to Firmware 3.1.3 shouldnt be a problem as I have the SHSH's for it, but in saying that, when I do get it back to 3.1.3, I'm wondering if I'm going to have any issues activating/hactivating my iPhone and then in turn, jailbreaking it so that I can then unlock it.
Is anyone able to shed some light on this? Would be mostly appreciated!!
My Q's/Notes
1. Since my iPhone at present is Activated, when I downgrade to 3.1.3, will it require me to re-activate through iTunes with a proper AT&T sim? Is there a way around it?
2. As I understand it, Spirit will be able to Jailbreak my Iphone when it is at 3.1.3 but only if it is already activated? Is this correct?
3. Once Jailbroken, there should be no problem running UltraSnow to unlock carrier?
Thank you very much for reading this post and I hope I get some replies!
This is my first time ever posting on a Forum, usually I just read others problems and find a solution!
Please be gentle!
Thanx again.
