I just recently jailbroke mine and my girlfriend's iphone 4's to ios 5.0.1 untethered. Previously, facetime was running fine on jailbreak ios 4.3.3 on both phones. But now everytime we try and facetime with each other, the caller can see the other person, but the person receiving the call either has a frozen screen showing the answer and ignore buttons, or just a plain black screen. I don't know if this is due to a cydia package we both have installed or what. I'm starting to think I may just have to restore and re-jailbreak both phones, which i would like to avoid. If anyone can shed some light on the issue, that would be wonderful. Thanks!
