Ok, so you might have restored your iphone 3gs using 4.3.3 ofw(official firmware) or cfw(custom firmware) using sn0wbreeze and also it might went into DFU mode loop. NOT recovery. All there could be a black screen.

I had also faced the problem problem with my 3GS. And I fixed it using redsnow beta 0.9.10b3.

  5. Create custom firmware preventing baseband update

    This will create a custom firmware file that will prevent baseband upgrade in the same folder with “NO_BB” prefix in the file name.
  6. Start TSS server using Tiny Umbrella and restore the newly created custom firmware using iTunes.

That's all! Now Jailbreak the device using the same version of Red Snow.

The iDevice in your hand (iPhone 2G, 3G, iPod Touch) is factory fitted with ARM Cortex processor having more Hz speed than you think. But that has been underclocked to provide effective Battery life.

Overclocking iPod Touch - iPhone 2G/3G/3GS  CPU?

That is clear that the processors fitted in the device are not fully harnessed, but it is possible with overclocking process. But your device should be Jailbroken tp process that method. The actual processing capabilities of iDevices are :

iPhone 2G/3G = 600 MHz (underclocked to 412 MHz)
iPhone 3GS = 833 MHz (underclocked to 600 MHz)

Steps to Overclock the CPU (iPhone 2G, iPhone 3G, iPhone 3GS, iPod Touch)

  1. Using a SSH tool like Filezilla or iPhone Folders navigate to
    System/Library/System/System Configuration/PowerManagement.bundle
  2. Rename file “com.apple.SystemPowerProfileDefault.plist” to  “SystemPowerProfileDefaultbak.plist” or whatever different.
  3. Reboot, and your iPhone/iPod Touch would Run on native Processor clocks.

Note: Increasing the clock speed would degrade the CPU’s lifespan by several minutes. However, since the device is not designed to handle the heat generated at higher clocks, we recommend you to terminate apps if device appears to overheat.
