I updated it two 2.1 instead of making a custom .ipsw and puting it in restore mode. Now i can't jailbreak/activate it, it says slide for emergency but my unlock stayed so i still see t-mobile as my carrier. every time i use pwnage it says i succefully enters dfu mode but itunes gives me an error 2001. I have tried quickpwn and that did not work either. any help would be greatly appreciated.
