Can I boost/improve reception on my Droid? With a rooted phone and an app you can overclock or underclock your processor.  Also, off Android, with some hacks you can boost power of a wifi router and wifi antenna.  It seems to me that if you can do those things you could boost the reception of your cell antenna some how.  Am I right?  If so, how?
Not really to do with actually altering your reception per-se, but you can update your PRL (preferred roaming list) of your phone for newer cell towers which might give you better reception.  On Verizon, dial *228 and follow the prompts.
