I developed TalkMyPhone, an open-source app that enables you to control your phone from google talk. It's like android-notifier on steroids, since it brings almost the same features and you don't need wifi/bluetooth enabled.
I can't post links since I'm new here. Google for talkmyphone or look for it on the market.
Developers: I'm open to contributions
Users: please use the issue tracker for suggesting features
I don't have many non-french users since the info did not spread very well outside of french blogs, so I'm posting it here. I hope someone will find it useful and write something about it.
