Without owning the phone I can't say but it looks like it may slide or clip off somehow. Looking at the pic on my phone, it also looks like there is a black/white ribbon cable attached to it on the left? When I view it on my PC later I will be able to see better. I would be very surprised if it needed to be soldered on, but I could be wrong. If someone does get their's repaired in a service centre, they can ask and let us know or even just send an email to a place offering this repair and ask them.
