Hector Trochez, those are both EMI filters.
FL2_RF 68OHM-25%-0.5A EMI Filter beads available at places like this
FL7_RF 120-OHM-25%-450MA EMI filter beads available right here. Hope this helps, good luck.

Thank You!! I aready place an order to fix my iphone. I really appreciate your help with this. Question this is solder by two sides each right?
It actually solders on both sides to the surface of the board
Does it have a circuit beneath or is there a hole in the board? So you mean to say it solders a pice 100% to the board?
No hole in the board. Those parts are called surface mount devices. The traces run through the layers of the logic board. The components connect to the traces by soldering either end to the surface of the board, check on here http://en.wikipedia.org/wiki/Surface-mou... for more info:-)
Hello, Thanks for the info, I ordered Part FL2-RF from Mouser and it came black color, the one in the board it's light green yellowish. it looks a bit smaller too.
