How to stop then delete the unfinish app?

[blackwind]

Hi there, ive got a friend who just install the bible addon app into his iphone 3gs. The addon is too big took him nearly 2hrs still going. and seem not able to delete or stop it all.
All it has the gray icon with loading.... on it...

Is there any way to stop it from installing and delete it off?

Cheers

Hold the power, home buttons until the phone shuts off. Then just turn it back on.
