Jay Freeman (saurik) has been a busy man lately. for the past two years. for a while now. His latest project to come our way was just released less than an hour ago – a way to finally downgrade your iPhone 3G[S] from 3.1 (with a few “well, if”s in there) to something currently jailbreakable (like 3.0.1).
Apparently iH8sn0w managed to find a way to provide the ECID signed to all users who have not had time to save it. This will make it possible to downgrade your iPhone 3GS firmware from 3.1 to 3.0. What is written below is solely and exclusively for the iPhone 3GS owners who have installed by mistake firmware 3.1 and are interested in getting their certificate in order to run the Jailbreak (when it is ready to DevTeam).
With less than three weeks left to the AT&T’s self-imposed “late summer†deadline for MMS on iPhone, Apple is hastily putting the finishing touches to the iPhone Software 3.1. The update will enable MMS and modem tethering via AT&T’s cellular network, in addition to over Bluetooth and copy-pasting video files.
