If you're holding out for the iPhone on VZW, you'll be waiting longer than 3 months. Mass production isn't slated to start until September, setting the launch up for the all too profitable holiday season. In 3 months time, you will see a new iPhone, but it will be AT&T's new rendition.
Personally I think the Incredible will be the device to have. I love the Android OS...although the rumored iPhone 4.0 OS running on the VZW LTE network will support multi tasking between 3rd party applications.
Just some food for thought.
