Movies on 7710

[sordid]

Hi guys am about to buy a 7710 and am keen to make phone movies with the view to even setting up a phone movie festival eventually. Anyone else tried to make films on their phones or used a 7710 specifically for this? Also are there competitions out there for this sort of thing already? And finally, what's the best deal for 7710s here? I found a £30 a month deal on 02 with £100 upfront for the phone can I do better?

Thanks
