Tablet PCs had not yet been sold to consumers
"RIM determined that approximately 1,000 BlackBerry PlayBook tablets (16 GB) were shipped with an OS build that may result in the devices being unable to properly load software upon initial set-up," RIM told Crackberry.com.
The majority of affected devices were dispatched to retailer Staples and have thought not to have been sold to consumers yet.
"The majority of the affected devices are still in the distribution channel and haven't reached customers. RIM is working to replace the affected devices. In the small number of cases where a customer received a PlayBook that is unable to properly load software upon initial set-up, they can contact RIM for assistance."
The tablet PC has not yet hit UK shelves but has been on sale in the US since April.
The Playbook is the first tablet PC from RIM. It has 7in WSVGA capacitive touchscreen with a resolution of 1024x600 pixels and runs off a 1GHz dual-core processor.
The PlayBook will also benefit from 1GB of RAM, plus up to 64GB of internal memory. As with most tablets, the Playbook will have a GPS accelerometer, a six-axis motion sensor and a digital compass. It runs the BlackBerry Tablet operating system and is capable of 1080p high-definition video capture thanks to its 5Mp main camera. It also has a secondary 3Mp camera and an HDMI out port.
In the US, the device costs $499 (£306) for the 16GB Wi-Fi version, $599 (£367) for the 32GB model and $699 (£429) for the 64GB Wi-Fi version. However UK pricing and a shipping date has not yet been released.
