Do a search for Google Wave on the App Store from your iPhone or desktop client, and you'll see an application called just that pop up, ready to be installed as soon as you fork over $0.99 (or €0.79 in my case). One caveat: it's not built, authorized or in any way endorsed by Google. Spotted by Stuart Dredge over at Mobile Entertainment , the unofficial Google Wave iPhone app seemingly slipped past Apple's usually and notoriously rigorous quality assurance and trademark compliance team and made its way to the App Store ( iTunes link - up to you to decide if this is something you want to pay for).
