BlackBerry outage hits Cingular, T-Mobile, Nextel

Research in Motion's BlackBerry email network was down on Friday last week for roughly four hours. The outage affected BlackBerry service on three carriers: Cingular Wireless, T-Mobile USA, and Nextel Communications. The outage affected some, but not all, BlackBerry users on these networks. Verizon Wireless and Sprint, however, said their BlackBerry service was unaffected. RIM claims over 2.5 million subscribers for its BlackBerry push email service.
