Last night I dropped my brand new MyTouch 4G into a pan filled with water. I do not mean it got a few drops of water on the cover, but actually dropped the thing submersing it completely into a pan in the sink. This happened mid-phone call so I promptly retrieved the soaking device, ended the call, and shut it down. I instantly removed the back cover to let the battery compartment dry out. Early I had complained about how difficult the batter cover is to remove, but to my surprise there was not a single hint of liquid or even moisture anywhere near the battery.
The build of the phone seemed like high-quality (metal cover and all), but you never know until it is put to the test. If I had purchased many of the other wide slew of phone choices last week, I would be calling the phone insurance company and coughing up $175 for a replacement.
To that I say thank you HTC! Not only is the 4G fully featured with the fastest phone OS available, but it is well-build with quality in mind. Alas no more rickety phones with sub-par components to keep the price down.
