Today I got some condensation on my iPhone 4 and immediately afterwards it appeared that the phone was not working properly. Finally I figured out that the issue was simply that the phone thought that headphones were plugged into it when in fact there were no headphones plugged in. This caused numerous issues including the touch screen sounds to not be heard, me to not hear when people called me though they could hear me, the iPod to not play through the speakers, and any other sounds that you would hear directly through the iPhone speakers. After tooling around with the headphone jack I was able to get this working properly again as explained below.
My wife has a Google G1 phone from T-Mobile and she couldn’t get it to turn on the other day. It was stuck at a screen with the Android logo on the front and pressing any buttons would not resolve the issue. I decided to remove the battery from the G1 cell phone to make sure it completely rebooted.
Removing the battery was a task in itself. There are a bunch of videos to explain how to do this but even with the video it was hard to remove the case that covers the battery.
