iSource Browser

iSource Browser is a source-aware web browser for the iPhone & iPad. It is a fully functional web browser with the following additional features:
- HTML source view
- WHOIS lookup
- DIG lookup
- HOST lookup
- HTTP Headers - all request and response headers with status codes
- Javascript debug console - inspection and debugging of WebView controls
- Full integration with Email, SMS, Twitter, Hipchat, Wunderlist, Asana, Fancy, and more!

As with any web browser, you can surf to any site on the web as you would in Safari, with the added bonus of transparency. With a tap of the screen you can view a page's HTML source, it's HTTP request and response headers, DiG & host information, as well as information detailing who owns and administers the site (whois).
However, iSource's most powerful function is the new Javascript debugging console, where you can inspect console messages, query the DOM, and more! Best of all, it's free.
iSource Browser is a must-have for any IT professional!
