iPhone 3GS mainboard issue with the connector / ribbon #7

Hi all...!

I'm having some trouble to connect the #7 connector/ribbon in my 3GS main board...

In the beginning, I found out that the Dock Connector Assembly that I ordered for a few bucks, from Hong Kong, didn't fit... Even the #4 connector didn't fit also!

But now, I found out that the tiny dock in the main board where we have to connect the #7 connector is kind of broken... Like you had a broken circle and so it's kinda loose... So, the connector won't stay fixed... It is always coming up again... This means that I won't have proper GSM signal :(

Any thoughts how to fix this?

Thanks in advance!
