Google's hedging their bets when it comes to the mobile phone space, and why shouldn't they? First it was reported that the much-hyped gPhone is probably "just" a Google OS for mobiles, and not an actual Google-branded handset. I'm actually not all that disappointed by the news, and it makes sense given Google's platform sorta-neutral way of doing things. A gPhone OS that could be installed on many a branded, locked, or unlocked handset is far more flexible - and potentially a much more penetrating way to deliver ads - than a single gPhone piece of hardware.
Then came the introduction of iPhone-optimized Google Calendar and RSS Reader apps. Google has created a new instance of their calendar app that detects if you're using an iPhone to access it and, if so, serves up a newly-refined version of the UI more suited to iPhone. It's pretty nice, but I still prefer the built-in iCal app.
Also, Google has released GWT Feed Reader, a feed reader app built on Google Web Toolkit and AJAX technology. It's Open Source so you can muck around with it if you're a supergeek type. Check 'em out:
