Wearable on Monday teased a rare new storage add-on for the iPhone and iPod touch. The AirStash behaves much like a USB flash drive with a removable SD card for its storage but has a wireless connection that lets it share its data with one of Apple's devices, even when not plugged into a computer. The approach is pitched as a way of storing documents and especially media away from the limited storage of the iPhone or iPod itself without losing access.
