Hey everyone, I'm new here, and a new iPhone user. I purchased a used iPhone 3GS, it was jailbroken when I bought it, so I am unsure what it is jailbroken with or how to find out. It is also unlocked. Anyways, my question is: I inserted my bell sim card, SMS works, browser and data works, but I am unable to send or receive mms. Whenever I try to send a picture to someone, it looks like it will send, but when the status bar reaches about 90% of the way, a red arrow appears beside the picture and it never sends. The apn settings are set correct for bell, can anyone help with this please?
