Android hints & tips

Following is a list of hints & tips that will make your daily life with android a bit better. Hopefully you will find this list useful and will save you a bit of time. I'm going to update this list every few days. If you think that something is missing or is incorrect, then let me know about it.
Note that I currently own an HTC HD2 phone which doesn't natively support Android, though I am using Android builds from XDA Developers that run on my phone. If you are interested on running Android on your HTC HD2, then visit android.hd2roms.com
