iPhone 4 No Service - Hardware Capacitor Problem - Look picture

[AceDK]

Hi to all,

this is my first post here. I heard about this forum on another website...that hear are professionals and they could help me maybe.
So my problem...i have bought an used iPhone 4 which is factory unlocked and jailbreaked. When i put my sim card inside i can use
WIFI without problems, but i don't get phone signal...always searching and no signal - no service.

So i decided to open the phone, and look...

- i see a broken signal antenna which was not connected anymore (I will buy a new one and replace it)
- the battery bracket connector was not there - somebody removed it and lost (I will buy a new one and replace it)
- i don't see the small blue capacitor-coil...and there shold be another small capacitor (smd)...look at the picture (?????)

Picture: http://oi46.tinypic.com/n532i8.jpg

Can somebody tell me if this is normal that there is no capacitor near the antenna connection? I looked on other pictures of iphone logic boards and
saw, that they have a small blue capacitor there and also another one capacitor, which is same size but not blue.
Should i buy new smd capacitors and solder on the board or? What are the suggestions...and what type of capacitor is this...what mode, how many V and what capacity in uF?

Thank you guys for your help in advance!

capacitor is not important, replace or jumper blue coil

Thanks for the answer. What do you mean jumper blue coil?
The thing is i don't have this blue coil at all on my mainboard, as well i don't have the capacitor left, from this blue coil.
And another thing...is this blue coil a normal capacitor?
