I have a big question...Now I bought my HTC desire with the Maxis 3GB data plan...is it possible to upgrade it to the RM99-unlimited data plan?

Is the anyway to change the way we unlock the screen of desire?

let's say I want to do unlock the screen like this:
1. tap any where on screen
2. slide the bar/press whatever button on screen to unlock it

thanks for the advice!!
