PlayBook OS 2.0 can do e-mails solo

Canadian electronics firm Research In Motion has launched its new tablet device called PlayBook OS 2.0 that corrects a previous oversight, media reports say. The e-mail function in the previous PlayBook could only operate if the owner\'s BlackBerry phone was in the vicinity, as the device relied on the phone to relay e-mails to it. That meant if the owner of a PlayBook happened to leave the phone at home while traveling with the PlayBook, the device could not download e-mails. Owners of the tablet who did not own a BlackBerry phone were out of luck. Their tablets could not receive e-mails at all. While the PlayBook OS 2.0 corrects the oversight, the Times said the tablet\'s operating system remains incomplete as it does not allow for sending free text messages using the firm\'s system called BBM, which stands for BlackBerry Messenger. RIM has said updates to allow the tablet to run BBM will be made available.
