With all the antenna issues (atleast discussed) in the iPhone 4, there have been a lot of people getting annoyed that they would have to get bluetooth headsets. Um guys, you're overlooking something!!! The iPhone 4 comes with earbuds with a built-in mic. I use it all the time when making calls! It works great! Now i'm not the antenna isn't an issue, but most people i know who have an iPhone carry around earbuds with them in their pocket. So just use them! It's healthy for your brain too because you aren't frying it with the cell phone microwave radiation.
