Research In Motion has updated its 'financial guidance' for the current financial quarter that ends on 28th May 2011.

The company says earnings per share are likely to be lower than the figures previously forecasted.

Mark Bridge writes:

We've had another short working week here in the UK... although not necessarily if you're working in retail. The reason for that shortness was a combination of Easter Monday and the Royal Wedding – an event that was rumoured to have its own mobile phone jammer.

As well as having another short week, we've also had another week of financial figures.

Google has augmented its Google Talk instant messaging app to include video and voice chat for Android phones.

The new service enables consumers to make video calls over 3G or WiFi between phones or from a phone to a PC. Text chat from the person you're talking to will appear in front of the video on your phone's screen.

Application store analyst company Distimo says Google's Android Market has overtaken the Apple App Store when it comes to free applications. It's calculated that Android currently has 134,342 free applications while the Apple App Store has 121,845 free applications for iPhones.

Distimo says the Android Market will become the world's largest app store (in terms of the number of applications) in around five months if all application stores maintain their current growth rate.

The four mobile application stores run by Apple, Google, Nokia and RIM will generate $3.91 billion (£2.35 billion) worldwide between them this year, an increase of 65.7% from 2010 according to IHS Screen Digest. Apple will be responsible for 75% of this market.

In 2008, the app market was worth just $207.33 million.
