okay, so i just got my incredible in the mail yesterday and was going over the phone inside and out. absolutely a beautiful phone. lightning fast, and super smooth. my old phone the moto droid couldn't hold a candle to this phone. anyways...the one thing that i didn't like about it was speaker sound levels...if you listen to it without the back cover its really loud and sounds great. but the hole on the cover for the speaker is super small. if you take the back off and look at the actual size of the speaker youll notice it is about as big as your pinkey thumbnail. however the hole that the sound travels through is about as big as a tip of a ball point pen. I think its pretty ridiculous and figured there was plenty of room for upgrade. in fact, i have done this on several other phone that ive had in the past and had complete success.
So i got the tip of my soldering iron and carefully rounded the hole out about twice as big as what came from the factory..i got a razor blade and cut off any excess plastic and made it nice and smooth. I then got a small metal screen that you can get at any hardware store, colored it black and glued it behind the cover and VIOLA....
now some of you might be a little hesitant to go at your brand new phone with a soldering iron, but really its no big deal its really only the battery cover and they sell brand new ones on ebay for 22.95 shipped.
honestly the sound from the phone is WAY louder, crisper and more clear with the hole being larger and it doesn't really look like i did anything to it. i might try to make it a little larger to see what more i can get from it, but for the time being im really happy.
