IPad 3 was gift with ISP (Verizon) setup. No longer have Verizon service. New carrier (Comcast) works fine with apps purchased after change enabled. However, original apps will not update since they look to sync with Verizon. Trade off is to delete old app and repurchase same app (connecting to Comcast) tHat I already paid for (with Verizon setup). Is there any way to rid the Verizon connection from the iPad?
