Eco-iP4: Accessories for the iPhone dont have to be complicated technological marvelssometimes theyre as simple as a well-folded piece of cardboard. Thats the idea behind the Eco-iP4, a small stand for the iPhone 4 and 4S that displays your device at a reclining 45-degree angle. The business model here is slightly unusual: Make a donation via PayPalno specific fee is mentionedand the developer will send you a PDF of instructions on how to make the stand, using either A4 or American Leather cardboard.

GoSmart: There are two lines of $25 styluses on the way from GoSmart: the 300 Series and the 200 Series. The 300 Series looks like a rocket ship in your hand (and also includes magnets for attaching to metal surfaces), while the 200 Series looks more like a traditional pen. Each is designed for precision use and comes with Teflon-coated metal tips that glide easily across the screen of your iPhone or iPad without leaving scratches behind. Both models are available for pre-order, but dont ship until Aug. 8.

iStabilizer: The $60 Dolly helps users shoot professional-looking video on the iPhonejust mount your phone on the device, which includes four inline-skate-style wheels for rolling across flat surfaces to create smooth tracking shots.

Klipsch: Klipschs new $100 Image S4i Rugged Headphones are made to take a beating, using rubber moldings for all-weather usability and extreme weather conditions.

Optrix: The $99 Optrix XD Sport transforms your iPhone into an action sports camera.

The case comes with a mount, letting users fasten it into place and shoot pictures and videos of themselves in action.

Padacs: If you own an iPad for on-the-go use, but a Windows-based machine for your desktop-computing needs, well, we wont judge you. (Just kidding: Well totally judge you.) But youve probably noticed that the USB port on most Windows computers dont provide enough juice to charge your iPad. Padacs is looking out for you with the new $20 RapidCharge cable, which makes it possible to charge your tablet when its connected to a Windows desktop. A status light shines blue when syncing, green when charging, or red when youre putting to much strain on your USB port (or iPad). The company doesnt say how the RapidCharge works this magic, but it ships on July 25.

RHA: Still looking for an upgrade from Apples signature white earbuds? RHA is offering the $50 MA450i, in-ear earphones that include seven pairs of silicone eartips to get the best fit. The company also says the RHA are designed for durability, crafted from solid aluminum. The earphones feature an inline remote/microphone for controlling your music and making phone calls, and the MA450i also comes with its very own carrying case.

USBFever: This accessory provider has several new products for iOS users. One of the coolest is the $23 Retro Camera Style Back Cover for iPhone 4 and 4S that, well, makes the back of your phone look like a camera. (Remember when cameras didnt have phones?) Also new from USBFever is the $50 Car Floor / Seat Bolt Mount, which lets drivers and passengers view an iPad in landscape or portrait orientationparticularly useful for folks who use their tablet as a navigation device.
