do all older iPhones screw up on ios 4?
I got this phone from a friend that quit turning on. I brought it home conntected to itunes nothing , then a flash white screen. I took it apart and saw that it seemed like the battery had maybe leaked. So I soaked and scrubbed it dried it ,viola it worked. Except the phone would shut off after about 5 minutes and i noticed the battery percent would react weird during boot. I've read about the os 4 messing up the battery and the speaker is low which i've read too. Are all versions of ios 4 going to have a problem on the older iphones or am I gonna try to have to downgrade back to 3 to see if this is the problem I like the ios 4 but if it won't work causing it's pushing it too hard then no choice.

did you replace the battery? or did you just clean it up? if you didn't swap it I'd do it now..your problems sound battery related. People wouldn't leave a leaking battery in their car..same principle here.
