Bryan Betts tracks his mobile phone and soups it up for group video calling, while Liam Proven tests the strength of Apple's Lion. Version 10.7 of Mac OS Xor'Lion', as it's informally known is the biggest update to Apple's operating system for its Mac computers since 2006. Many of the changes are internal and largely invisible, although they might cause concern for existing users who are upgrading. Lion won't run programs for PowerPC-based Macintoshes only 'Universal' or Intel-specific application will work. Java has gone, too, although Lion will automatically download it if one try to run a Java application. Lion requires 2GB of RAM and won't install on the first generation of Intel-based Macs with Core Solo or Core Duo chips. With mobile phone malware in the news recently, with Android in particular attracting attention from cyber criminals, it is time to consider protecting the phone. Once installed and registered on the phone you can do some things locally, such as start a virus scan or backup your contacts and calendar to Bullguard's server.
