Greetings, I'm new to the iPhone and new to this forum. I came from a BlackBerry Bold 9700. I used the speaker phone 90% of the time and prefer it because I can put it in my shirt pocket and do other things while talking on the phone. But since switching to the iPhone4, everybody I talk to says the sound quality sucks, both while listening to my speech and while talking themselves. Actually, the audio (my end) of the sound is better on the iPhone than the BB, but literally everybody I talk to tells me they HATE the sound they're getting from my iPhone in speaker phone mode. If I switch to normal (non-speaker) mode, they tell me it sounds fine. I have tested this repeatedly, switching back and forth between speaker and non-speaker mode with several different people and the consensus is that the speaker function sucks for the person I'm talking to. Any suggestions?
