I've been trying to send some picture messages on my iPhone 4S today since about 12:00pm this afternoon and up until now (1:50pm) it hasn't worked. I'm located in Jersey City, NJ and a Verizon Tech has told me it's not a problem with my bill, and there are no problems with the service in my area. I've tried to text 5 different people the picture message and it hasn't gone through to anyone. My iPhone 4S is jailbroken and on the latest firmware and I do use Bite SMS although I have the option selected to send my messages through my carrier's service NOT through Bite SMS. And I have not had any problems with sending picture messages up until today. I've also tried to send myself a picture from both my brother's phone (One is an iPhone 4S the other is some Samsung or HTC Phone). If I were to take my phone down to the Verizon Store today if they want someone to have a look at it, is there any way they could tell I was jailbroken if I were to restore my device back to factory settings?
