If you are having problems connecting your iPod Touch to your mobile phones that’s installed with Joikuspot or Walking Hotspot, always getting “unable to join the network [insert network name here].”

Chances are your iPod Touch’s software is the older version (1.1.3), the solution is to update to 1.1.5 or shell out $9.95 for version 2.0.2 (as of this posting). You can update it with the use of iTunes.
