Here's one for you hackery types -- changing the resolution of your Android phone's screen through software, just like you can on a desktop monitor.
You have to be rooted, so take that to mean there's a chance for things to go boom if you don't follow the directions to the letter, and insert the standard disclaimer -- this is at your own risk, and nobody is responsible for things that may or may not go wrong.
If that bit of dirty business didn't scare you off, have a look up there and see the before and after pictures on a very messy and cluttered Evo 4G screen (for maximum effect, maximum widgets must be used!). You'll need to decide if the benefit of having more info on large screens outweighs the effect this can have on widgets and other oddities.
Want to try it for yourself? Of course you do -- look here in the forums for a well written and thorough set of instructions. While this was written with the Droid X in mind, the hack works on most Android handsets. Android 2.2 required! [Android Central Forums] Big thanks to DaRkL3AD3R for this one!
