Now that the phone is pre-ordered and will be here June 24th for me, I've started to think about some cons of the iPhone 4. The biggest thing is that the vibrate will probably suck. The vibrate on the 3GS was VERY low and, now that it's smaller in size, will likely be worse on the 4? This is not a deal breaker for me, though, even though I only use vibrate. Still excited.
