The ear speaker on my iphone 4 stopped working- I can only make calls now with a headset or on speakerphone. I have a genius bar appt today and am scared they will find out my phone is jailbroken. I tried to restore 2 times to get rid of the jailbreak but it didn't work. Do you think they will run diagnostics and see it's jailbroken? I am also on 4.2.1 now- should i just upgrade to 5.0 without restoring (since I can't)?
