Hey, I just bought a blackberry tour 9630 for Verizon Wireless. And the lcd has brown spots and the housing's keyboard is fading off. I was wondering, when I repair it is there a difference of the LCD and the housing that makes a difference between this and the Sprint version? Or do they work universally? As well, for the housing I heard ones from China suck, is that true? Someone let me know please, it'd be greatly appreciated thanks.
