i used greenpois0n to set up my cydia and i deleted the loader and the cydia worked fine. then i downloaded ifile and mywi. i got rid of ifile, but i wanted to get rid of the mywi. with that being a big hasel that no one knows about. I thought removing cydia would get rid of the problem, and all i would have to do is re install it. but no. i try to re jailbreak it. and the loader symbol will not show up.
No i dont have any apps on my iphone that will fix the problem.

so im guessing i have to fix it from the computer.

i use a windows computer. i would be ever thankful if someone could help me and the many others out there with this problem.
