Removing built in applications from Android Tablets?

We’ve received another email today that has got us stumped! Janar writes:

I bought Samsung Galaxy GT-P1000 tablet in Saudi Arabia. In this tablet some of the applications like Quran, prayer timings, direction for Khbha etc. can not be removed or uninstalled. Can somebody give solution in this regards.

I had no idea that this sort of thing would occur anywhere in the world, but if you know how to remove these applications from a Samsung Galaxy tablet please comment to this post and we’ll try to let Janar know the good news.

Alternatively, if someone would like to send me a tablet so I can have a play, that would work just as well
