Spanish with an Argentinan accent, although it is not exclusive to Argentina (it is found in a few other Central and Southern American countries), varies in only one aspect from the first write up.

The double-L ("ll" as in ella, llama, or estrella) is not pronounced y but rather a soft j with sort of an "sh" quality.


Just a bit of advice: if you are anxious not to sound like a "gringo" pronounce your ts like ds and your vs like bs. Those, as well as those mentioned above, are the details that will help you smooth your Spanish into a decent accent.
