Great news for all iPhone 3GS owners with the new bootrom and firmware 4.0. iH8Sn0w managed to jailbreak.
Check your bootrom version here .
Unfortunately, only two facts overshadow such a joyful event.
Firstly, jail is still bound, i.e. after turning off, restarting or discharging the device’s battery, in order to “revive” the gadget, you will have to connect it to a computer with the sn0wbreeze utility. And secondly, only those who have saved SHSH from 3.1.2 can do this operation.
Everyone who, according to these criteria, can not afford a jail, can not be upset. This is only the first swallow, further more. [ iclarified.com ]
