If the inductor is in place and your phone has intermittent GSM failure, I would not replace it. Make sure that all the parts for your antenna are properly placed and connected. Of course, you can try and place a jumper with a circuit writer pen, or better yet, replace it. I personally would replace it. It is a coil and not a fuse, and I am pretty sure Apple placed it there for a reason. Do a Google search and you will find a few companies that will sell the inductor. Take a look at this video to see what you are up against.
As for reballing your IC, it may be difficult for you to obtain the proper template for a reball. This, of course should not stop you from trying a reflow.
