User Tips,
if you're wondering what tool is best fit for you redsn0w or sn0wbreeze,
if you're using at&t and don't plan on unlocking you're iPhone, then redsn0w is best fit for you,
if you're using tmobile,simple mobile,h20 don't have an at&t sim card to activate or at&t service, and want to upgrade you're firmware with out updating you're baseband and rely on a carrier unlock then sn0wbreeze is the way to go,
unlocking you're device
if you wish to unlock you're 3gs, and are currently on an unlockable baseband such as 5.14, 5.15, 5.16 or higher, you will have to enable the option to install ipads baseband 6.15.00 firmware then install ultrasn0w from cydia
if you're on 1.59.00 baseband for iphone 4
or 5.13 baseband for 3GS
you will need to follow my video how to upgrad to 4.3.1 or 4.3.2 and preserving your unlockable baseband by creating custome firmware without a baseband update
