Here is what I have on my user agent under Regex, taken from a few sites: Mozilla/5.0 (Linux; U; Android 1.0; en-us; generic)
AppleWebKit/525.10+ (KHTML, like Gecko) Version/3.0.4
Mobile Safari/523.12.2
I personally don't see it working on my HTC Dream, though. Think that list is a problem? Should I reduce it to just "android"?
