The iPhone's screen is a bit larger, at 3 1/2 inches, but the Storm offers slightly higher resolution (480 x 360 pixels).
The iPhone comes with 8 or 16 gigabytes of internal storage; the Storm has just 1 GB but can take memory cards up to 8 GB.
Apple decided on 2 megapixels for the iPhone's camera, but it lacks video. The Storm offers 3.2 megapixels plus video recording.
Both phones have GPS and maps, but the Storm adds optional turn-by-turn navigation software called VZ Navigator.
