My iPhone is jailbroken but I dont think this should matter. iPhone says Im using 44 GB of my available 55 GB. When plugged into the Mac, says: 16 GB of music 1 GB of pictures 4.5GB of apps 2 GB of documents 3 GB of other.. With basic math, that adds up to 26.86. I have a 64 GB model and my phone is saying 10.72 GB free... where the **** is my other 18.14 GB???
