[Q] Cannot Find out Appname APK

Hello,

in short: I would like to find out apk names to listed apps.

In Settings->Applications->Manage applications there is a list of all installed applications.

For example there is an app called "Bebbled" listed in "Manage applications". How do I find out, what the name of the corresponding apk file is ?
In /system/app there is nothing to find with the name "Bebbled".

It is a stock mobile with android 2.3.6, no further applications installed by me yet.

Thanks in advance,
Peter
