my wifes iP4 has the good ol returning yellow spot on her screen it was there the day we got it then went away a day later and now is back a week later again. i tried to make an appointment at the genuis bar for today to get everything taken care of but the soonest they can see us is friday which doesent work for us we cant make it in until sunday other than today. i called and asked if they could squeeze us in and they said all we can do is come and and do a stand by and hope someone doesent show up or someone finishes early. anyone done this before or know if its even worth wasting the time waiting there? she said it could be 10 minutes or it could be hours. any advice guys thanks.
