cookie support in blackberry os 4 and above

I've developed a web application for mobile. As I'm new to mobile web development I'm little worried about the support for cookies in smart phones. Application is targeted to be viewed in iPhone, Android supported mobiles, blackberry OS 4 or above versions. I'm not aware of all features which are support on our desktop PC browser and mobile browser.

My application is ready I've tested on my desktop but not on any smart phone. I don't know JAVA and used PHP to develop the application. Monday I've to give demo of the application to client.

Can any one will tell me whether worries are acceptable.. Can I give demo without checking/confirming 开发者_如何学Gothe app on blackberry device(as client want to see the application on blackberry OS 4 and above). How should I test app on different devices. with buying any device...

Please help me...

Cookies are supported by the BlackBerry web browser, even going back to version 4.x of the OS.

To test your application, you can download a BlackBerry simulator from:

For older simulators (4.x for certain), you will need to first start the MDS simulator, which allows the phone simulator to connect to the internet through its web browser.

You can download the MDS simulator package from here:

With web application testing, the BlackBerry web browser doesn't contain many discrepancies between the simulator and the physical device -- the simulator's browser is a good indicator of how your application will feel on the real BlackBerry web browser. It has all the same configurable options, so you can test how your application behaves if the user chooses to turn off the cookies in their BlackBerry browser.
