My phone was stolen and shockingly returned (there are some good people out there!) but now all of a sudden I am getting a constant pop up Error Message that states this: Error Code 67 Registration Failure...". Someone please help, it's driving me crazy and I cant get on the internet. Sprint is worthless for customer support. For those technically savvy people out there, do I need to worry that someone is getting into my personal info on my phone (ie emails, pics of my kids, etc?!)???? Help please, if I see another error code I am going to pull my hair out! And the though of people having access to my phone from a distance is scary. BTW, I have the HTC Evo Shift 4G. Technical stuff is definitely not my strength so any help is of great appreciation.
