Sami420, that would be the Broadcom BCM5976. Check step 13 of this guide. It is a BGA IC and will need to be replaced through a reball method. For that you need special equipment as well as very strong skills.

I threw a motherboard from another iPhone into the it and the costumer was very happy as his phone was only days old :)

Are you sure that the touch IC was bad? It could be any number of other issues near the digitizer connector. I was just working on a 5 the other day and one of the 0 ohm resisters (super tiny) was missing and power was not getting to the digitizer.
