What application in iOS generates these user-agents?

I have to perform user-agent (UA) to application mapping for a few iOS related UAs. Most of the application user-agents have the name of the application in them, like for Facebook App it seems to be

Facebook/3440 CFNetwork/485.13.9 Darwin/11.0.0

But I see a lot of generic UAs. I cannot find the applications related to these. Can someone tell me what generates these. These are, for example:

Apple-iPhone3C1/812.1
Apple-iP开发者_JAVA百科hone2C1/812.1
Apple-iPhone3C1/807.4
Apple-iPhone3C1/810.2 etc.

Also, is there any open app or resource that maps UAs to Apps for iOS?

Those generic UAs don't belong to an app. It's the id of the hardware and the WebKit version.

This part is the hardware model:

iPhone3C3 = 4 (Verizon)
iPhone3C1 = 4
iPhone2C1 = 3Gs
iPhone1C2 = 3G
iPad2C3 = iPad 2 (Verizon)
iPad2C2 = iPad 2 (AT&T)
iPad2C1 = iPad 2 (WiFi)
iPad1C1 = iPad
iPod2C1 = iPod Touch 2
iPod3C1 = iPod Touch 3
iPod4C1 = iPod Touch 4

This code

UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectZero];
NSString *ua = [webView stringByEvaluatingJavaScriptFromString:@"navigator.userAgent"];

gives you this string:

Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_3_5 like Mac OS X; en-us) 
AppleWebKit/533.17.9 (KHTML, like Gecko) Mobile/8L1

which contains a WebKit version (533.17.9 in the example).

All these UA strings and alot more are out there and can be used to identify specific configurations/combinations etc. (sometimes even the current carrier!)... check the list here.
