If you’ve been reading about Google Gesture, the new hand-writing based search mechanism on android phones and have not been able to find it to download, there is nothing to worry about. If you have any OS version that is lower than 2.0, the app will neither install nor will show up in your Android market. Similarly, if you are outside US, the app is expected not to work.
So if I use the QR code on my good old G1 with an older OS, the QR code and URL is recognized but no download is available for my phone. Time to buy a new android phone?
This fact is also confirmed on the discussion groups here on Google Gesture’s own discussion forums.
If you have a device with 2.0 OS and you are in US, you can download the software from http://gesturesearch.googlelabs.com/download.html .
