Apple Iphone wont reboot

[anime4ever]

I have just jailbroken my iPhone 4 which is 4.2.1 I am worried because when rebooting (apple logo) there is a circular loading thingy that appears and it gets stuck there. I would like to add that I had not activated my iPhone 4 before jailbreaking it (I did not insert a sim card yet ), it still had the "connect to iTunes" logo. I would like to get help on what I am supposed to do now that its been approx 20mins and the iPhone did not boot, please. Forgot to mention I used redsn0w

One post is enough.

That's because you currently have a tethered jailbreak. You have to boot it jailbroken each time.
