iOS: If you’re travelling and need to find a wireless network that you can use to log in to your VPN and check email, pull up a car reservation or verify a hotel booking, 4sqwifi is a new iPhone app that — as long as you’re already signed up to use Foursquare — can show you which check-in points have free Wi-Fi or Wi-Fi networks you can log in to.
Based on the premise of the TV show How I Met Your Mother, developer Mihai Parparita (he of Google Reader and Gmail user script fame) created Intersquares, a service that compares your Foursquare check-ins with any other Foursquare user to determine all the times you’ve been at the same place at the same time, whether you knew it or not.
We’ve previously suggested that social check-in service Foursquare can be more than just annoyingly self-involved, including its use as a self-tracker. Turns out it’s seriously simple to track your wanderings, for expense sheets or other means, with Google Maps.
Free access to social networking sites has been used as a carrot to attract mobile users before, but 3′s latest deal is pretty comprehensive: free access to Twitter, Facebook, LinkedIn, FourSquare and MySpace for contract mobile customers.
Office 2010 officially goes on sale on June 15 next week. Getting a cheap copy isn’t that easy, but Sydneysiders have the chance to try and win a copy of the Home and Business edition if they can get to Martin Place next Tuesday lunchtime.
