Well the file you said you had that is 80mb, isn't that the .apk file? Which is the file you install an then you have the game. What other files are you talking about that you would use winrar for?
is the 80mb an .apk file? If not I'm guessing its a .zip or something, but use winrar and extract it an then see if there is another .apk file in it that could be the game.
PS
when i try to install the 80mb sims 3 it says that it could not be viewed. free up some space on your phone and try again, while i still have 102 mb left right now
i freed up some space and have 102 mb left
but whenever i try to install it says that i cant view it and need to free up some space on my phone while i have 102 mb left
Can you free up anymore space? Like when I had to install the leaked need for speed, I had to clear up 100mb for the file then another 100mb for the install itself. This could be the same instance here.
