A lot of people like the idea of being able to carry things like photo or video files with them on their iPhone, but depending on what capacity model they have, may not necessarily want to take up memory on the phone with those files. That’s where ego & company’s Hybrid Series USB Case comes into play – it’s a case for the iPhone 4 and 4S, with a built-in USB Flash drive.

The scratch-resistant case protects against dings and drops, while still offering access to all of the phone’s ports and controls (it is not waterproof). Integrated into the back of it, however, is a removable USB Flash drive. These are available in 4, 8 or 16 GB capacities.

Users can load the drive up at their computer, then have the files close at hand – but not taking up space on their phone – when they’re out and about. It should be pointed out, however, that since the iPhone doesn’t have a USB port of its own, files on the Flash drive can only be accessed via a nearby laptop, tablet or desktop computer with a USB port ... so, you might not want to use it for storing photos that you plan on showing to your friends next time you’re at the bar.

The Hybrid Series USB Case and its Flash drives are available in six mix-and-match colors. A case with a 4GB drive is priced at US$34.95, while the 8 and 16 GB versions sell for $39.95 and $49.95, respectively.
