Hi all! I have had my G2X for about 1-2 months now. It's my first smart phone...I am learning that settings may depend upon the phone, the operating system being used, and the apps being used. I have figured out a lot on my own, but I have a few questions: 1. How do I upgrade my operating system to the latest version (without too much trouble)? 2. Is there a "dropped call" notification on the G2X? Or an app to get one? I don't drop calls too often, but when I do, I don't realize it. I'm tired of saying "Are you there? Can you hear me now?" My old regular cell phones usually had a great hang up sound. 3. I'm having issues connecting to--and staying connected with--my WiFi. I've checked all my settings. Some days are better than others. The other cell phones in our household (same provider, different phones) don't have an issue with WiFi. 4. My battery usage seems erratic. Today I went from 100% to 30% in 4 hours. I know it depends on what you're doing...I'm overwhelmed by all the apps that guide you and I don't want to download too much junk. Is there a recommended way to get a handle on my battery usage? Thanks in advance.
