Funny ****, I just read in a newspaper how an iPhone4 user broke his phone by taking it outside on a cold day, It died, R.I.P. The guy goes to the store, and what do they tell him, "sorry iPhones can't handle less then 32 degrees, and thus is not covered by warranty". My nephew's IP3g died too I just found out, he was outside with it in the cold. What a piece of crap phone Sorry, buy a real phone next time, not a fashion statement.
And yes, the warranty will claim it can't be used below 32 degrees. Go Apple!
Wow.. that is weird.. Even more weird is that i was outside with my phone hear in memphis for the last 2 hours in 20sum degree weather and i had zero problems... Try taking it out of the sweater and off the charger... for a little bit.. Then continue to hold both buttons...
If that doesnt work.. take it up to the apple store.. DONT tell them you left it near the window.. Just say, u woke up and it was on your nightstand on the charger, but wouldnt turn on..
