Weird Jailbreak issue with iPhone4
so i used jailbreakme.com, successfully JB'd and then after a little while decided i didn't want it. went to restore from the backup i did right before JBing and when it finished it still had cydia on there. i tried restoring again and same thing. then restored from a backup from june 25th and still, cydia was there. is there anything i can do besides restoring to factory settings and syncing my stuff back? if i wait for an update from apple will it just take cydia off my phone? never had this problem with JB before. any help would be great.
