Is it possible to replace just the front panel of the iphone 5 without replacing the whole digitizer/assembly ? my screen is not scratched at all, only the bottom left corner of my iphone has a crack. I have been quoted rediculous prices for the front replacement and they say the whole assembly has to be replaced...is that true ? I dont mind spending tedious hours trying to pry away glue to make it cheaper for me in the end.

Thanks
