Hi, I have the 4S, running on 5.01 with the Absinthe Jailbreak. As of this morning anytime I make a call on the phone, once I hang up the phone freezes. The phone stays black for a while and I wait it out, it will take me to the main screen but no buttons work. If I use Siri once it ends the phone freezes and the same as above. The only way to get it back is to do the reset of hoding the top and home button till I see the apple. I do not get the phone crashed message. I haven't installed anything new on the phone from Itunes or Cydia for a couple of weeks and this problem has only started as of this morning. Any ideas?
