I have been using my first smartphone, the D2G, for about two weeks now. I really like the hardware and feel of the phone. I have not been very happy with the operating system though. It just doesn't respond as quickly as I would like it to. One of my biggest complaints is the unlocking of the screen. This is a simple function that should work smoothly since it is used every time the phone is used. The slide to unlock function has a delay from when i touch it to when it responds, and then it takes about an extra second or two to actually unlock and bring m Also, text message seem to frequently not send. I type out a text, hit send, and then a minute later i get a notification saying message not sent which is really frustrating. I know the battery life of smart phones are never good, but I have to charge mine almost twice a day. I do not use any social networking widgets that continuously sink or any app killers and the battery still drains very quickly. I was leaning toward an iphone 4 at first, but i chose the D2G because I got it for a much cheaper price and it has a physical keyboard. I am really trying to love the D2G, but at the moment I don't. Maybe my experience will change as I use the phone more and more.
