A bit of a problem has occoured. Basically, I like modifying things, so I decided to get a white back, white front ect.. I got the parts, 1st I snapped the LCD screen, so I got a new one, but now, when I press the home button/sleep it will come up with a grey screen, also when I charge it, it makes the noise :/ I have no clue what is wrong as it really confuses me. Anyone had this problem before? Thanks so much!
