Today's Tech: UK waits for Apple's iOS 7, GigaOM Structure:Europe cloud event live and BlackBerry's big phablet debut

Today's headlines have understandably been dominated by Apple's release of iOS 7 into the wild - or rather, the UK's wait for the new operating system. However, there's been plenty of other major business for us to talk about too.

BlackBerry has today launched the Z30 smartphone, a 5in phablet which the company is trumping as its "biggest, fastest and most advance" device yet. The smartphone will be running BlackBerry10 OS version 10.2 and feature a full touch screen Super Amoled display along with a 1.7GHz processor with quad core graphics. The struggling Canadian firm also says that the smartphone will offer up to 25 hours of mixed use battery life. The BlackBerry Z30 will be released first next week in the UK and Middle East, and all other regions over the coming months.

Tesco is set to unveil a budget tablet on the 23 September under its new Hudl brand, with the supermarket giant sending out invitations to a launch event stating "we've got something to show you." Tesco has not yet revealed any details about the device, but specs have been leaked to the British Tech Network, reportedly by someone within the company. According to British Tech Network's source, the tablet will have a 7in display with a 246ppi 1,280 x 720 resolution, a 1.6GHz quad-core Processor, 16GB of storage, 1GB of RAM, stereo speakers, a 3-megapixel camera at the back and two megapixels at the front.

The UK government is testing an alert system that sends messages to mobile phones to inform the population of national emergencies. O2, Vodafone and EE are all working with the Cabinet Office to roll out the pilot scheme that will see around 50,000 people receive the messages, which will be marked as "test" to avoid confusion. "Ensuring that local areas receive quick accurate information in the event of an emergency is crucial to an effective response and the information that we receive from these tests will help us develop systems that local emergency responders will be able to use in the future," said Francis Maude, minister for the Cabinet Office.
