Longer Video Record Time On 9800

Well, I know that you can find hacks to download into the phone and edit them like HTML to change some settings on the phone...I was wondering if anyone had a hack to have a longer video recording time...Or if anyone has a hack that they have found helpful for their 8100 or 9800, please post it here.

i've never heard of any such thing and almost positive hacking your phone = void warranty.
