I have a 32gb 3GS and i got a error message this morning sating my iPhone needed to be restored. I did a soft reset and it came back on with my theme still active but on the emergency calls only screen. I tried DFU and standard restore with no success. I made an appointment with apple tomorrow at my local store, my question is, will they be able to detect that I had or have a jailbroken iPhone? My concern is because I haven't been able to fully restore so I'm not sure if the jailbroken software if still on the device. Thanks for your help in advance.
