Hello! Please help me! I need know the specs of the resistor in circled in the images. Thanks!

OP, I can't really tell much from your picture. Do you have a clearer image? I'll try to Google a close up of the logic board, but you need a chip-resistor; do you see any printing or numbers on it? You can calculate what you need at this site if you can find any inscription on it.

Look down to .
1. R8_RF 100 K 1% 1/20W MF 201
2.DZ12_AP 100PF 0201 6,8V
Amazing, how did you find this, Proxy?? I didn't notice the schematics you attached at the bottom, too, just the diagram. Thanks for that, and for doing the hard part! Can't imagine how long the BOM must look like on the 4 and 5.
OP, per Proxy's info, the part in 1.) is a 100KOhm 1/20w (0.05watt) resistor with 1% tolerance in a 0201 package (0603 metric). It looks like it is in a metal film (MF) composition, based on the info. This part is found in Proxy's attached schematic diagram at the bottom right between SMDs FL7-RF and FL5-RF.
I believe the second part, 2.), found in the upper right of the schematic diagram, between SMDs J7-AP and J21-AP, in the little SMD array running vertical, appears to be specs for a varistor rated at 100pF (picoFarads) at 6.8volts in a 0201 package (0603 metric).
Here is a link on DigiKey for finding resistors with the desired ratings:

Thx for full info about parts
i repair iphones but i´m not a technician
i read schematic and search in a google
and my english is very basic
I need any parts for iphone 5 : can you write info about this for me?
