I had a Motofone (also called F3) for the last 7 years. It started with a two week working battery life. It's a pain to text message on since it only shows 4 or 5 characters on, but it just worked as a reliable phone. Finally switched to an iPhone 5 after it became vital for me to have full Internet access 24/7 for work. If it weren't for that, I'd still have my F3. I love it as much as I love my iPhone 5.

You can still find some of them on eBay. I'd offer mine, but I'm keeping it as an emergency (911) phone for my car.
