Today, being as stupid as I am put my iPhone 4 in the microwave for 3 seconds. It turned off & I got it back on by putting it on the charger. Now, my lock button won't work & my phone won't detect wifi, those are the only problems I'm aware of as of now. I feel like the stupidest person on the planet. Any tips / advice on what I should do? Your help would be appreciated. (PS~ a new phone is kinda my last resort)
