About to purchase a D2G in one hour. Questions though first! Hello. This may seem completely stupid and irrational, One hour to get a phone and ask questions... But my parents want new phones before a trip! Anyways. Here they are. I have recently decided, along with my parents, that we want to purchase droid phones. For my parents, the droid 2, and for me, the droid 2 global. I am not new to the android community, I had the T-mobile G1 for a while, then ditched it for the Motorla Cliq, (ha.) and now I want to go to Verizon and get the D2G. I am also an avid android fan, keeping up on many android news websites, so android as a whole is not something I am inexperienced with. (Sure, I am not a developer, or coder, but I know the basics) I just have a few questions about the D2G. I know that the battery of the D2G can fluctuate, depending on how much the phone is used. In my case, I use my phone a bunch, online, emails, texting, etc. So I know my battery life probably won't be amazing. I am however, worried about my parents, who are totally new to the smart phone experience. So, on a quick tangent, how is battery life for the D2? And for the D2G, how can I improve battery life, other than in the settings, brightness, and not using many apps at once? I hear there is something called an extended battery, that helps, but makes the back of the phone "weird" (For lack of a better word). Is this true? If there is an extended battery, where can I purchase one? Now, onto the second question. Overseas calling. I know that because this is a global phone, I can use it overseas, but I have heard that the sim card needs to be "unlocked". What does this mean? Can I not just travel and make calls? Do I need to do something more? And lastly, what are you D2G users final CONS? Not Pros, because I know that the Pros are large in number, but CONS? (Besides battery life) Is this a good phone to get?
