Google has launched a Chrome to Phone extension for Google Chrome. The extension allows you to search for things on your desktop computer, and immediately send them to your Android handset. Whether you're looking for web pages, maps, phone numbers, videos, or directions, you can immediately send it to your Android phone. The beauty of it is that it does not rely on tethering. You do it all OTA.
There is one catch with Chrome to Phone. You have to have Android 2.2 installed on your device so if you haven't got the froyo update yet, you're out of luck.
