Can't switch on iPhone4 after jailbreak

[mached88]

Hi, I bought new Iphone4. I tried to jailbreak it and everything was going great. I did it succesfully but when I turned it off, tried to put my simcard and turned it on all what it shows is greenpoison logo and keep vibration every 4 seconds.I tried to restored it trough iTunes but I couldn't because some error occured.Is there any software how I could make recovery but not use iTunes???

I don't know how to do what you are talking about. Only way i forsee here is that you put your phone in recovery mode, update or restore it using itunes and after that you can jailbreak it again.
But if your jailbreak is a tethered jailbreak you will need a booter to boot up your device which i think it is not your case.
To put your phone in recovery mode, push down both power button and home button untill you see the apple logo on the screen, then you release the power button and keep pressing down the home button untill your screen display the itunes icon.
