Has anyone experience this? Ive had it happen over 6+ times to me in 24 hours. What happens is that I don't touch my phone for like 20 mins or so.. then it will go into suspend.. I then try to wake it up and it just doesnt turn on. Volume/Home/Power buttons do nothing. I actually have to physically hold the home and power button for over 30 seconds to get the Apple logo to appear and for it to reboot. Anyone else experiencing this? My phone seems to only have this happen in colder enviroments like.. 60-70 degree ambient temperatures.. In my pocket and pulling it out it has never had this happen.. but sitting on my desk or in our break room it has occurred to me a few times.. Not sure what is up. Anyone with this issue?
