iPhone browser that supports web workers?

Came to realize that iphone's safari browser does not support javascript web workers (multithreading). Am wondering whether there is another brow开发者_StackOverflowser for iphone that does support this feature.

(i do not own an iphone, so i cannot just download and try all available browsers)

Although you're not likely to find an alternative browser that supports web workers now (pretty much all the alternative browsers for iOS use Safari's engine underneath, due to restrictions on code execution), reports indicate that web worker support is going to be in Safari for iOS 5. See:
