How I can install skype on my iPod 2g

I beleive u can't, if u check itunes facebook and skype both require iOS 4.3 which all first and second gen ipod touchs have 4.2.1 or less, so they can not run anything that requires 4.3. I just found this out and can't use half the apps i have purchased and use to work for my 2nd gen touch.

I doubt you can download skype but you could use safari and log into facebook that way
