Summary: Unfortunately does not compete with the smartphones available. Very few apps to download, screen is near impossible to see in sunlight due to it being reflective mirror-like glass, and there are spelling errors (yes spelling errors) in the error messages (i.e., "Error: Message could not be send"). I am truly disappointed that Samsung would put their name behind a phone like this.
Summary: I had Blackjack II for almost 3 years and was very happy with it. Jack is like some half-hatched early prototype of Blackjack II. I cannot download Google mobile app, which I had on Blackjack II with no problem, due to "not having permission" to install it. I keep getting text messages from unkknown numbers with pure gibberish. Half the time the AT&T home page does not download when starting the Internet Explorer, displaying an "error message".
