So I recently got a jailbroken iPhone 3G, and it was able to send picture messages before my dipsy self went and screwed it all up. I tried downloading a fake 4.3, and I later uninstalled it and put the 3.3 (7E18) back on it, but now it won't send picture messages, just emails. Should I just unjailbreak it? What should I do? Also, I'm not sure if it matters but I have T-Mobile, 5.11.07 modern firmware, and cydia.
