Sounds like you need a jailbreak then to renew the feeling! But in order to do that you need to find and install whatever it is you wanna do with your device 🙂
Btw, if you jailbreak you can always upgrade later on to 5.1 so that is not a problem. But you will most certainly not be able to jailbreak until the dream team comes out with an new jailbreak. But setting your device back to a normal state is the least problem, that you can always do.
But you will not be able to jailbreak with this new jailbreak forever, but rather do it until apple stops signing the 5.0.1, otherwise it's too late. So it's the other way around of what you might think when it comes to the case you where thinking 🙂
