like i downloaded and installed the recent jailbreak last week, the one where you didnt need a computer, thing is it was semi tethered, so i ended up restarting my phone cause it was going slow, after that i couldnt open cydia, it would open for half a sec then close, so today i went on my phone and reset everything, all setting and data(everything) i didnt back up, i set my iphone up as a new iphone, when i got back to my screen the cydia app icons were still there. i dont have access to a computer, how do i get this off my phone? if the phone company sees this they will void my iphone
