While video chat is a new feature of the iPhone 4, trying to hold the phone while chatting that way could lead to movement in the video. Elago's M2 stand is a good feature-specific accessory that stabilizes the iPhone on a table. The stand holds the iPhone vertically and horizontally.

It is for $24.99 on Amazon.com.

As the name indicates, the Bumper accessory is a rubber and plastic frame that fits around the smartphone and has openings to the buttons and connectors so the smartphone is fully functional. However, it leaves the screen exposed.

At $29.99, the accessory might be expensive. Equally functional cases from companies like are available at cheaper prices.
