but I thought multitouch could be written into android apps? So it’s just the apps developed by Google that won’t include multitouch. Example: Dolphin browser http://sites.google.com/a/mgeek.mobi/browser/
Presumably this is because of that pesky Apple patent on multi-touch gestures. Google are steering clear of anything close to the patent claims to avoid lawsuits, but if app developers want to test how close they can cut it, they're free to try.
