Title:

"No Service" after repair, Missing Component.

Text:

Hi everyone,
we've received an iPhone 4s in for repair and about 3 people have looked at it.
It has been to a repairer previously who replaced the screen and rear glass, and also didn't replace any of the brass pressure connectors. (we havent replaced these yet)
The issue initially was that it would be continuously "searching", Unless it was connected to a wifi network..... and we would get at least,"No Service" (we tried the manual time setting, without a wifi connection, but this stays on searching) it seemed for a while we fixed that after a reset and updated to 6.1.2. but after the next disassembly, the issue came back.
We have now restored through iTunes and it seems that has resolved the constant "searching" issue, (it seems).
We still have the no service problem. we took the phone out on a collection run rom another customer, It did manage to get a very weak signal and receive a text message saying welcome from the carrier. but nothing since
We have replaced the antenna taped to the speaker and ensured that its is connected firmly. Looking around today we have noticed many places mentioning to check for board components. We have found a missing component which "looks like" a resistor (pictured)

Could anyone identify this component,
Is it related to a celular signal? (is it the likely cause of this issue.
Can it be replaced?
Where can we get one (in the UK)?

So, we'll reclaim one from a faulty motherboard.
