I have a Sprint iPhone 4s iOS 6.1.3....using a GPP Sim Interposer so it'll work on AT&T/Straight Talk. Worked great for several months and then my iMessage stopped working...so I did a factory wipe/reset and now the iPhone won't recognize any sim in the sim card slot...(Because I didn't activate it with the original sprint Sim? I've lost the original sprint sim..didnt think I needed to keep it...oops)..
Any ideas/suggestions to get my phone up and running with GPP again?
