The launch of the much awaited BBM app has been delayed, but there were a lucky few who were able to download it on the iPhone before it was pulled off the App Store. The BBM for iPhone appears to have the same interface as on the BB 10 platform. Those with existing accounts are asked if they want their BBM to be shifted to this device, others have to create a new account. Once you approve, all contacts are moved here. The app allows only messages, voice notes and images, as it doesn’t support screen share or video calling like on the BB devices.
