Genuinely, why do you want an iPhone? Is it because most of your friends have one or you like the apps available for it? Are the voices in your head telling you to "buy the iPhone because that's what Jesus would do." BTW: If it is a small chip on the screen maybe the plastic overlay can be replaced? (The Nintendo DS has this. Actual lcd and "touch" senser is sandwiched behind a plastic sheet). You may get more if you are capable of repairing it.
