BlackBerry has confirmed that a new version of BBM hitting iTunes within 24 hours will work on Wi-Fi-only iOS devices, including iPad, iPad Air, iPad mini, iPad mini with Retina display, and iPod touch devices. (See update below)

The first version of the company's messaging iOS application was suitable only for Apple devices that had cellular connectivity, either 3G or 4G. That meant iPhones and SIM-loaded iPads were okay, but a large amount of the market still couldn't use it.

Speaking to SlashGear, Andrew Bocking, head of BBM, said the company was pleased with the rates of adoption and reiterated that the app exceeded 10 million downloads in its first 24 hours.

Expanding it to the last remaining Apple device owners will surely increase that figure. BBM added 20 million users in one week thanks to its cross-platform roll-out, and we suspect the addition of the iPad will help the number grow. 

Update: The app update has been released.
