What's a Semi-Tethered Jailbreak?

Most jailbreakers know of the two common jailbreak types: tethered, and untethered. For those of you who don’t, a tethered jailbreak is when you’re forced to run jailbreaking software to boot up your device, and an untethered jailbreak is when you can turn your device on/off regularly. The latest version of redsn0w (0.9.6b4) introduces a type of jailbreak that is fairly new (it was used for early iPod touch 2g jailbreaking but not lately due to userland exploits/kernel patches) that many people were not aware of: a semi-tethered jailbreak. A semi-tethered jailbreak is when you can boot your device normally, but MobileSubstrate add ons (infinidock, infiniboard, winterboard, etc.) will not work until you run redsn0w again. If you want to jailbreak you newer device (iPhone 3gs new bootrom and up), you’re stuck with a semi-tethered jailbreak until comex can whip up another kernel exploit.
