The annoying thing about using Wireless@SG is you always have to login with your username and password through some website before you can start browsing. My flatmate recommended an app to make that cumbersome process easier, at least on my iPod Touch. SG Wireless is a little app that helps you login to Wireless@SG automatically. Once you’ve saved your login info in Settings, just open the app then it tells you if you get connected, close it. And you’re all set to use any of your apps that need Internet connection without opening Safari and having to key in your Wireless@SG user+pass combo. I wonder if there’s a desktop widget that can do the same thing.
Update: For iPhone, iPod touch with OS 3.1 and up (except first generation devices), you can now download apps from the 3 Wireless@SG providers that would generate a certificate for your device. Installing the certificate will make your device automatically connect to Wireless@SGx without you having to input any password. After the certificate is installed, you can just delete the app. App Store links below:
