Signal loss - logic board

Hello,

I have a problem with my iPhone 4S. After trying to replace my battery i accidentally popped off a coil on the logic board. The link below show a picture of the logic board (yellow arrow is pointing to the part that i popped off)

Is it true that this is a RF coil? My signal is very volatile and changes between No Service and full signal at the same location. Is it possible to fix this? I do have the coil but have non experience with solder.

Thanks a lot!

Michael, your yellow arrow points to reference designator J4_RF which is a MS-180 RF Connectors / Coaxial Connector manufactured by Hirose Connector. It is not a coil, but nevertheless you will need to reconnect it. Check the datasheet on here, it will show you how and where the solder points are. Hope this helps, good luck.
