BlackBerry services collapse worldwide
A UK data server failure has sent BlackBerry devices offline in Europe, the Middle East and Africa, affecting millions of users.
The glitch, which is believed to have happened on Monday, is being blamed on a server fault at BlackBerry manufacturer Research in Motion (RIM).
The fault is affecting e-mail, messaging services and web browsing on the smartphones.
The affected users are served by Canadian company RIM's data centre in Slough.

BlackBerry has apologised for the problems and promised to fix the issue.
