Boy,they just keep pumping out new Angry Birds games.I have yet to play the first one on the tablet yet.They just released a new episode for the original angry birds a couple weeks back.
Some time back, I put AB Original, Space, Rio, Star Wars , and Bad Piggies, on my phone.
Over the following month, I played some of 'em a little.
Just haven't had any interest, since.
I just use them as a demo.
Yes, the single-core iPhone 4 runs the games fine.
Next time I upgrade/wipe the phone, they won't be restored.
