Hi all, I'm new to this forum and to the android system...I just bought a Droid 2 the other day and am really happy...except for the battery life (I've checked the other threads and implemented some changes to see if that'll help with the battery life). I have a question though. I added this widget (I think it's MOTO's widget) that lets you toggle bluetooth, GPS, wifi, brightness, and something else. I'm not sure what this something else is. It's two curved arrows forming a circle. Can someone explain what this button is and what it does? At this point, the only thing I need running is my gmail. I'd like for the phone to consistently check my gmail for any new emails (that's the main reason I got the phone). Thanks in advance for your help!
