Google started sending out the initial batch of invites to its hotly-anticipated new Google Wave service this month - and has quietly launched an iPhone-friendly version.
TechCrunch discovered that users can point their iPhone's Safari browser at wave.google.com and get an optimised version of the service, not dissimilar to the iPhone web app version of Gmail.
It also works on Android handsets, as you'd expect given that it's Google's big new thing.
The mobile version can also be saved as a bookmark to the iPhone's home screen, allowing it to be launched as if it was a regular iPhone app. This makes use of Apple's feature allowing full-screen web apps on iPhone, when launched from the homescreen.
Explaining Google Wave could take a whole article in itself, but in a nutshell, it's a communications service mixing in elements of email, instant messaging, document editing and online collaboration - all in real-time.
Given that people aren't in front of a computer 24 hours a day, making it cross-platform from the start is a sensible move.
