Londoners queue for new iPhone
Blackberry says it's getting more and more people back online all the time after a week of problems.
Taking the battery out for a few seconds could help you restart.
Meanwhile hundreds of people have been queuing through the night outside the Apple store on Regents Street to be the first to get the new iPhone which is now on sale.
Pre-orders of the phone hit 1 million in a day - the 4S is said to be quicker and offers state of the art voice recognition.
