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.

Ship dates and pricing aren't public for the AirStash, though it should have a more formal appearance at CES this week. [via Chip Chick]
