Those of you who have installed JailbreakMe on their iPhones might be running into some problems, specifically MMS and FaceTime completely disappearing from the device. Obviously this is not normal but Comex is working on it. I am sure he will fix this in the next few hours. In the meanwhile, sit back and enjoy your newly jailbroken iPhone.
I will keep you posted as soon as JailbreakMe is updated and fixes this issue with MMS and FaceTime.
UPDATE: This has been fixed. More info here.
