I'd say it's stable and reliable, as long as you don't drop it in the toilet. It's kind of a pain in the butt, though because of the battery life. You have to keep turning off features, and back on only when you want them, and make sure to plug it in every chance you get. It's ironic, that the phone has this really great 4G service that makes internet faster, but in order to get any battery life out of your phone you have keep that turned off unless you're specifically using it. Which means in order to use your fast internet, you have to first stop and wait for the fast internet to be turned on and connect, which kind of makes your total internet time not any faster.
