JGoogle is nothing special. I think it’s more a proof of concept for the developer than an actual application.
Jgoogle is a full screen browser, without any extra features.
The app doesn’t support zooming and doesn’t show any navigations bars.
On starting the app you just typ in the address you want to navigate to and jgoogle will open it full screen.
The app must send a certain user-agent with it that asks for a wap compatible version.
I think this browser is handy for the people who don’t have EDGE and who are still using GPRS.

1) You can locate the app in the installer.

2) When you start the app, it only asks you for a webaddres. After that there are no more options.

This little app is available in the Installer.app through the Big Boss packaging source, see our sources page.

Enjoy
