Your only way is if you have the version that was compatible on your computer such as in the recycle bin/trash or in a computer file backup. In that case delete the current version that is in your iTunes App library and replace it with the older version. Then sync.
The moral is to be careful when updating apps in your iTunes library. Only update to versions that are compatible with your iPod.

Or, as I suggest, never upgrade to the latest firmware. Had I not done so, everything would be fine as all the apps worked. The problem is the discrepancy between what 4.2 will do and what 5.0 requires. The 2nd gen iTouch will not run 5.0 so the best choice is to leave things alone or buy new hardware -- obviously what Apple is trying to force.
