FM transmitters are typically made for specific devices, such as the iPod or PSP. For those uncomfortable with linking their ability to transmit audio to a proprietary accessory, the new iCast adapter from iStuff will plug into any common minijack output and broadcast sound to nearby radios on a user-selectable frequency. The iCast is also independent of a car or wall power source: it lasts for up to 18 hours on a AAA battery. Shipping today, the iCast is available internationally from the UK store iWorld for £30 ($57 US).
