IPhone 4 problem! How can I undo this?
Okay so me and my gu friend Felix were texting earlier and I was just kidding around with him cuz he kept bothering me and I texted him,"okay stop". And then this link appeared that said," To stop Pinger texts from ### reply STOP to confirm". And stupid me, I actually texted STOP thinking that he had sent that link just to fool around with me. I found out it wasn't him because we were just messaging eachother on FB a while ago and he told me he can't send me more texts. The point is that neither me and him can text eachother. Please help me. How can I undo this? I have an IPhone 4.
