UA Parsing Is Incorrect - ipad 4.2 beta

[GoogleCodeExporter]

iPad 3.2 is not Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us)

Should be iPad iOS 4.2 beta

I wonder if there's any logic about the UA string we could use to detect it 
though, since it says OS 3_2 it's kinda tough

This actually happens with all early beta versions of iOS. I've added an 
additional check based on AppleWebkit version in my own ua parser. The code is 
in Javascript and not immediately usable in browserscope, but you'll probably 
get the meaning:

-----------

detected.os = {
    name:       'iOS',
    version:    1.0                    // If no version is detected, it's 1.0
};

if (match = /OS (.*) like Mac OS X/.exec(ua)) {
    detected.os.version = parseInt(match[1].replace('_', ''), 10) / 100;
    if (detected.os.version < 1) {
        detected.os.version *= 10;
    }
}                   

/* 
    Sometimes Apple releases beta versions that still have the old version number, 
    but they do have an updated AppleWebKit version. Below are the first version of 
    iOS in which each version of AppleWebkit is shipped. If the reported version is
    lower than the version expected from the AppleWebKit version, it is an early beta.
*/

var build = parseFloat(ua.match(/AppleWebKit\/([0-9.]*)/)[1]);
if (build >= 420.10) detected.os.version = Math.max(detected.os.version, 
1.1)        // 1.1
if (build >= 525.18) detected.os.version = Math.max(detected.os.version, 
2.0)        // 2.0
if (build >= 528.18) detected.os.version = Math.max(detected.os.version, 
3.0)        // 3.0 - 3.1
if (build >= 531.21) detected.os.version = Math.max(detected.os.version, 
3.2)        // 3.2
if (build >= 532.90) detected.os.version = Math.max(detected.os.version, 
4.0)        // 4.0 - 4.1
if (build >= 533.17) detected.os.version = Math.max(detected.os.version, 
4.2)        // 4.2 - 4.3
if (build >= 534.32) detected.os.version = Math.max(detected.os.version, 
5.0)        // 5.0
