Cannot retrive apps after installing CorbyPRO

Hello,

I have installed the Google Mail App in the samsung Corby PRO . It's installed fine and iI'm able to use it. But, after closing it, I cannot retrieve it again on my Corby. When i try to installed again, the popup tell me the app. exists on my Corby Pro.

The problem is that I cannot find Java apps afetr installing them. I mean i need kind of a shortcut or icon to launch them when ever i want to.

Please help.
