Another Blackberry outage

Users of the smart phone were reportedly unable to access any of their mobile data for several hours today.

Reports of users being temporarily cut off from BlackBerry service have been popping up on the Web.

BlackBerry users who are also customers of Sprint, T-Mobile and Verizon complained of slow e-mail or completely interrupted mobile data service. Corporate customers of Research In Motion did not seem to be affected.

Silicon Alley Insider got this statement from RIM: "Some customers using BlackBerry Internet Service experienced a delay this afternoon in sending or receiving e-mail. The issue has since been resolved and no messages were lost. RIM continues to investigate the matter. Service for BlackBerry Enterprise Server customers was not impacted. RIM apologizes to customers for any inconvenience."

Most RIM customers will remember the massive system outage in April that shut down their mobile e-mail service for several hours. The problem was blamed on a software upgrade, and CEO Jim Balsillie subsequently promised during an interview with eWeek that a similar glitch would never happen again.
