wisamalrawi, easy may not be the proper term for it. The GPS IC is soldered to the logic board via a BGA, which is a type of surface-mount packaging used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. So unless you have a BGA rework station, the proper grid and the proper IC, as well as plenty of experience, there is no easy about it. Not a DIY'er job....
