First of all the question is, how can i delete a software if i installed it and i don't like it? I am too new to the iPhone so i don't know..

The problem with the Categories v1.53 is that after i install it and make some tests, it has appear to my springboard a thing called "DemoApp" and i don't know how to delete it...

(My weDict don't work too..)

Thanks to all of you people, you are so helpfully.. (poor english)

noone know?

You can use the Customize app to hide entries from Springboard.

Other way to hide it:
in Categories go to settings, and enable "Allow Hiding Icons".
That's worked for me. If it is not for you, try Installing Customize.

from where at Customize?
