Foursquare is an initially addictive social-networking game, which is fun to play while you compete against friends and locals, earning points and unlocking Badges, and becoming virtual Mayor of popular places. At the moment it's little more than that, but things could change if it really takes off - which it looks like it might on its current trajectory.

If your mobile phone is your most important device (and it probably is), you should take care to protect it: especially if you use it for business. Norton Mobile Security offers protection and doesn't impact performance, and the Google Android app is currently free, so there's no reason not to try it.

1. Microsoft Office Mobile 7

• RRP: Free with Windows Phone 7 handsets
• Rating:

For the majority of consumers, Office Mobile doesn't offer a compelling enough take-it-with-you set of tools to justify choosing a Microsoft phone over others. For anywhere-access to my work, I'd rather deal with Google Docs, despite its limited mobile editing for Android and iPad, than have to grapple with SkyDrive or emailing files on a Windows phone. There's no live support available for Office Mobile if you're stuck, as is all too standard with software lately, but the online resources are thorough.
