there is no skype "App" it just is part of the system. what u need to do is
tap to just type
type accounts and tap the icon that shows up
proceed to add the skype account
once it finishes synergizing, type the name of whoever u want to skype with and u should see a drop down icon next to it. tap on that to use video, voice or just chat
if u are not familar with webos try using just typse for anything u want to do.
like instead of going to contacts to look up your contacts, just type it and it will come up. same with any apps your looking for and even indvidual websites~!
for example, if you come to precentral lot you can add Precentral to you search engines under just type. it will scan the site for you without u opening the site yourself~!
its pretty cool once you start to see just how great webos can be!
