I know that if you restore your iphone ipod ipad ect or whatever that you have jailbroken that apple will replace it with a another if you run into a problem with your device however i am wondering if there are any evidence if the jailbreak files are still left behind in the files system? As one time my iphone would not activate after a restore from a jailbreak before taking it to the apple store. so they took it to the back and ran some diagnostics for about 15 minuets said they couldn't find out what was wrong and replaced my phone. Do you think that when they ran diagnostics that there is a possible chance that files could be left behind from the jailbreak? i am just wondering and i thought i would tell you guys the store of what made me so curious about it.
