Sorry. I should have specified. The back speaker volume is very low.
I sort of fixed it though. When the iPhone 2G was released, people complained about the speaker (Apple has significantly increased the volume of it in the iPhone 4 though). A recommended fix was to actually break the little net around the speakers that keep dust out. I figured why not and did just the same. It actually got a little louder to my surprise. Anyway, it's still not loud enough to hear in places like the mall.
Oh, and other problems like the camera takes black pictures all the time, it sucks in general now (it used to kick ass), the volume sucks, my calls always drop when I have full bars of 3G (weird), market apps never download right, internet pages load when they feel like it, the lock screen never lets me enter my pattern without breaking (another weird thing), and it will always freeze. I also noticed that my sister's Verizon iPhone had faster speeds through the speedtest.net app.
All the problems aside, it still is a kick ass phone, but I'm kind of getting fed up with it. I hate having to pull the battery out three times a day just to get it to function properly. I've had it the day ti came out on July 15 (I HAD TO HAVE IT LOL!).
So, if you guys could help me boost the volume through software or hardware, it'd be apperciated. I tried the audiomanager app, but had no luck with that.
