Apple tightened security with iPhone 3GS and the latest 3GS hardware version is only capable of tethered jailbreak 🙁
Saurik, the man behind Cydia implemented a clever approach to bypass Apple’s insane security features of the 3GS! He explains the whole process in great detail here.
In short, all you have to do is :
Jailbreak your iPhone 3GS. Trust me it is easy, fun and super productive to jailbreak your iPhone and it is perfectly legal!
Launch Cydia on your iPhone 3GS
Click on ‘Make my life easier, thanks!’. If you don’t see it on Cydia, your life is already made easier 😉
Follow these steps to downgrade your iPhone 3GS firmware in the future.
Congratulations on securing your iPhone 3GS jailbreak from all future Apple attempts to break the jailbreak!

I have an Iphone 3GS, i've loaded the 3.1.2 custon firmware with no activation, than i've unlocked with ultrasn0w, using this new 3.1.3 ipsw hactivated will I have the same push notifications problems as 3.1.2 ? and if I use the 3.1.3 with no activation, and after i've activated I use ultrasn0w, is it safe ?
Kiran
You can try installing pushfix in Cydia to resolve the issue. 3.1.3 will be the same as 3.1.2…

help pls , i got iphone 3gs (new one ) and i made restore from i tunes without holding shift ,,
and my iphone screen is the( cable & itune icon )and emergency call only .. what can i do ??
kkiran
It means it is waiting for activation.
Do you have AT&T or the official iPhone carrier? If yes, launch iTunes and it shall activate.
If you don't have an official carrier, use Custom firmware to restore it to an activated firmware and get past emergency screen. Look for the unlock guides in the menu…

Your only option if you don't have an official iPhone contract is using custom firmware. If you have never jailbroken your iPhone 3GS, you can only use iOS 4 now. I will post the links to the custom firmware shortly.

I need more input. Spirit works with 3.1.3 firmware. You may also try custom firmware.

does this signature server work for those who a running Firmware Version 4.1 with baseband 5.14.02. anyone have any idea?
Kiran
It is a 2 step process : Jailbreak and store your SHSH files for all firmware versions before the release of the next firmware version by Apple.
If you have SHSH files stored at different firmware versions, then yes you can use Saurik's signature server or better yet, use TinyUmbrella. It will show what firmware you are eligible to downgrade to and the simplest way of doing so!
