Kanex: No matter how many iOS cables we have around, we always wish we had one more. Kanex seems to understand our problem, as it's selling iPhone- and iPad-compatible USB-to-dock-connector cables in packs of two for $25 or three for $30. Unlike some non-Apple cables on the market, Kanex says these are good for both syncing and powering up your iOS device.
Kensington: Yes, there are a million keyboard cases out there--so Kensington is trying to distinguish itself with a little style. Its $100 KeyFolio Pro 2 fits the most-recent two generations of iPad, and it comes in brown, red, and caramel. The device features a removable Bluetooth keyboard, as well as a velcro fastener that lets you prop up the tablet at an angle ranging from 20 to 70 degrees; when you're done, it folds back to look like a regular folio-style case. The KeyFolio Pro 2 can also be unfolded to prop your tablet into a display position without the keyboard.
Nike: Nike and iOS have long been linked, and now the sports company is deepening the partnership with three new products--Hyperdunk, LunarTR1, and Lunar Hyperworkout--that use sensors in your Nike shoes to measure your workouts and game-playing, and then wirelessly communicate the data to an app on your iPhone. Nike hasn't yet unveiled pricing information for its new line of shoes, but the launch of the product line occurs on June 29.
USBFever: If you want to capture images of small details, then USBFever's $21 Super 20X Macro Lens with Back Cover might be of help. The device comes with a back cover designed for the iPhone 4 and 4S; if you need to take a photo using the lens you can just screw it onto the case. The phone's flash will be blocked when the lens is on, however, but one upside is that the back cover is also compatible with USBFever's 8x telephoto lens.
