Yes, you can really solder the pins on the chip. I use a steromicroscope and you have to hold the board very steady. I use a soldering iron with a sharp point which is just the width of the pad.

Of course a steady hand is needed as well. It only needs a little practice with the right tools.

gpio15 right? gpio15 must connect gnd for esp-03. is it same on esp01 ?

For those of you with good soldering skills and a steady hand I've developed a system to give you 4 extra gpio pins that are on a firm socket rather than hanging wires off the pins.
It consists of removing the existing pins, replacing the 2 rows of 4 pins with 2 rows of 7 pins. Remove the 5th pin on both rows and solder the 2 rows in with the extra pins to the left.
Next solder fine wire from these extra pins to pins 9,10,12,13.

The extra pins are GPIO14, GPIO12, GPIO13 and GPIO15.

Wow! This is great. I wonder why they didn't include these I/O pins in the default breakout.
