Hello,
I have an iPhone 4s also with reception problems(1-2bars MAX), after taking the cover of, i noticed
the white component was completely loose (the one circled in purple on the attached picture, sorry to Varun Gargi for borrowing your pic, hope you dont mind)

anybody have a clue what this component is? or if it could be simply bypassed?
cheers
