To make it clear – it doesn’t come from RIM and it’s not a watchphone. Made by Allerta, inPulse is a BlackBerry smartphone accessory that connects wirelessly to your phone by Bluetooth and can show previews of emails, SMS and other messages (Twitter), together with incoming call details and alarms.

It packs 1.3″ full colour OLED display, Bluetooth v2.0+EDR, 150 mAh lithium-ion polymer battery (~ 4 days), glass lens and full metal body, vibrating motor, micro-USB port (for charging) and supports over-the-air firmware updates.

Works with any BlackBerry with OS 4.3 and above and can be pre-ordered right now for reasonable US$149.
