I just had my iPhone 3g jailbreak and downloaded a few things and now when i try to get in cydia it just goes back to the home screen. I have been on youtube and tried the "clear cydia list cashe" and that didn't work and I see people having a installer or ssh on their phones to fix it but i don't have any of that. I have even went back and re-jailbreak it 3 more times and it don't fix it? What else can I do? Please help! THANKS!
