iPhone 4 Quite Sluggish After iOS 5.0.1 Tethered Jailbreak

Hello Jayson, have you tried to hard reset your iPhone. In most cases, hard resetting is necessary on all gadgets and computers (not just on iOS devices). To hard reset, all you have to do is hold the Power and Home button at the same time till you see the silver Apple logo. Then just simply boot it in tethered jailbroken state using Redsn0w 0.9.9b8’s Just Boot option.

I am not sure if this has something to do with some of the apps installed on your iPhone but we are hearing some reports from our reader that their jailbroken iPhone get quite sluggish and unresponsive after installing SemiTether app. You should be noted that SemiTether is still in early beta stage and it requires a lot of time to get fully developed and working. If that’s the case, then I would recommend you to uninstall SemiTether on your device (through SSHing). You can also just simply restore and then rejailbreak your iPhone to ensure that you have got all fresh Cydia packages. You can refer to this blog post for the detailed iOS 5.0.1 tethered jailbreak using Redsn0w 0.9.9b8. That’s it! Good luck...
