I. do. not. believe. it.
I was erasing and restoring my phone after having it unlocked with my provider, and I have been having problems for FOUR frustrating hours. Multiple times it had an error pop up telling me it could not restore from iCloud backup, the verification codes would not send to my phone, and I was about ready to throw it through a window. I googled what to do as my final try, and I came upon this thread. Against my better judgement, because I usually do not believe this stuff, and I had nothing better to do, I read every single word of the thread. Not expecting to see anything, I looked down, and no word of a lie, it says 43 minutes. 43 minutes is better than it being stuck at "estimating" forever. Say a little prayer for my phone to the Apple Gods.
