I activated my new phone on Sept. 30. It worked fine till Oct 5th. It crashed with a black screen. It wouldn't do anything. If I pushed the sleep button or the home button a few times Siri would speak up and tell me "there has been a mishap please try again in a little bit." It never cleared. I had to go to a fast food emporium to get internet access, log in to iTunes, then hold the sleep button and home button and plug in with a USB all at the same time. Not easy to do but I pulled it off. The next day it crashed three times and has crashed at least once every day since. Once in iTunes it wakes the phone up and you can check for updates, reset to original settings and such. This is bs. I am running the latest OS and it still crashes every day. I am paying verizon wireless a lot of money to have a device that is unreliable, crashes, and becomes useless without warning. They really need to get this sorted out.
