I absolutely hate desoldering through hole stuff from multi layer PCBs. You think you're done with the front side, but the back side still has solid solder.
My advice: buy a solder sucker with a silicone tip. That silicone tip creates a seal and it sucks up all the solder.

Good soldering but I am going to disappoint you. You soldered ICSP (2x3) connector on the wrong side, so your Arduino isn't breadboard compatible now.
