missing componant

Can anybody please help with the missing component(s)? in the picture, what is it, a capacitor, what value? or is their a link workaround?
The components are directly behind the LCD connectors ie: on the other side.
I'm a fully trained surface mount technician working for the space industry, so re-attaching it is not a problem, but i cant find out the value.
Cheers for any help or assistance.
Its a 3G 8GB

No Sim detected in 3GS

After boot 3GS he say "searching" for network, but no sim is in :-)

with installed sim he said seraching too, ...

Reboot with sim, without sim, always the same. Tried with different sim cards. Always "searching"

Cleaned all on PCB, Sim contacts are clean. No broken Parts. All coils on Antenna connector are OK.

When connect to iTunes, iTunes say "No Sim installed"

Any suggestion?????

with original FW 4.2 itunes brings Error 1002.. kicked out of recovery with TinyUmbrella, system startet. Connect to itunes and than the message from itunes "Please put in sim card" (sim is in) , while itunes will activate the phone.
------------------
tried with newest snowbreeze with 4.2 FW, and than System startet. System is activated well, but than "no imei" and "no wifi". System is always "Searching"

it is the same, if a simcard ist placed in or not. All contacts on Sim Reader are OK. Test simcard switch, no effect. Absolutely clean board. Tried with differnd Simcard. Simcard all working in other phones.

i think it is the baseband ic defect...

infinite apple logo/need help please!!

I am a newbie to the i phone4 and had a buddy of mine jailbreak it last month. Today I clicked a link on Cydia I believe, and it asked me if I wanted to upgrade some of my apps. I clicked yes. Everything downloaded fine and than I was prompted to reboot which I did. Well I was never able to fully reboot and got stuck on the "white apple logo" screen. At times it will show the circle bar in front of the apple sign as if it's loading but nothing happens. After 5-10 minutes the screen goes black and than repeats the same process. I tried turning it off and home but no luck. I held the power & home key down until it turned off again, waitied, than tried turning it back on with no preveil.
Can someone please help me! Again I'm not real tech savy but I believe I had 4.0 or 4.1 OS. And I don't want to lose my saved information. I tried tiny umbrella to kick out of recovery but it did'nt work. Any information would be greatly appreciated!
