iH8sn0w has just released iBooty 2.1 which now fixes Waiting for iBSS issue which was mainly experienced by iPod Touch 4G/3G users. Many iPod Touch users were unable to boot their iDevices into tethered jailbroken state after iOS 4.3 jailbreak using Sn0wbreeze 2.3b1. iH8sn0w has also released Sn0wbreeze 2.3b2 which now adds Multitasking Gestures option in Settings app for all iDevices.
Note that when you jailbreak iOS 4.3 using Sn0wbreeze 2.3 (beta 1 or beta 2), it automatically creates iBooty directory along with iOS 4.3 custom IPSW file on your desktop. To boot your iDevice into tethered jailbroken state, iBooty 2.1 requires DFU file which is unique for every iDevice.
If you already have jailbroken your iPhone, iPod Touch or iPad using Sn0wbreeze 2.3 beta 1 and do not want to recreate iOS 4.3 custom IPSW using Sn0wbreeze 2.3 beta 2 to get iBooty 2.1, just use the download links below and follow this guide to put your iDevice into a tethered jailbroken state using iBooty software.
