What are some tricks/Apps/tips you've found or come up with for using your Android phone? What sort of things do you use your phone most for? I'm hoping to compile a nice list of useful tricks and etc that make Android more useful. Obscure and lesser known things are great, but really anything is welcome. [Edit 1] It's a list geared toward people who are new to Android and want to get the most out of it. This would include professionals who do a lot of emailing from multiple accounts, multimedia users who like music and video, and people who generally just want know everything their phone is capable of doing.
