We use Basecamp here at Macgasm to keep our contibutors on the same page. Up until now, we’ve been relying on native iPhone apps to access our information while we’re on the go. But as of this morning we now have a native web application that is optimized for the iPhone; 37 Signals has just announced that you can now use Basecamp natively from Mobile Safari.
As of today you can access Basecamp on the iPhone3GS, iPhone 4, and iPad directly from Mobile Safari. Basecamp is now optimized for mobile browsing, and they’ve implemented the web app with modern HTML 5 technologies. So, if you’re using a device other than an iPhone, you’re probably in luck, so long as it supports HTML5. All you have to do is log into Basecamp, and the website will redirect you to the mobile stylesheet.
If you still prefer a native iOS application to a web application, we would recommend that you check out Headquarters (download link after the video).
