Glad you got your phone working, if you ever have to do what I post make sure it is an AT&T go phone.
Put your cell phone in a pillow case, go out on the front yard, swing it over your head and scream like a chicken. Don't know if it will fix it, but the neighbors will be amused, and you will be paying homage to Dick VanDyke.
Another trick you can use (IDK if it's been mentioned) is take the battery out and put everything in a Bag of rice. We've done this several times and it works.Glad to know the oven works too!
Remove the battery and put it on a cookie sheet in your oven on the absolute lowest setting for four hours.
lol You actually went with the oven option and it worked? I thought the suggestion was just a joke. Careful you don't melt anything.
