Red light stays on busy. Having same problem with my fona + gps board, am I really bad at soldering or is it something else?

Some of the joints look teardop-shaped, which is a sign they may not have wetted the pads on the PCB.

Give them a dab of flux and reheat them. You should see them snap from a teardrop shape to a cone. Hold the iron to the joint a couple of seconds beyond that to let the heat and solder spread fully across the pad, then remove the iron.

Your joints are nice and shiny, so it looks like you have the iron at a good temperature and aren't overworking the solder. You just need to get a little more heat to the pad.
