Yes. Officially, every version up to Android 2.3 was for phones. Samsung wanted to make a tablet and made one with 2.2 and 2.3, even though Android did not officially support tablets for those versions. Android 3.x was a version just for tablets (Honeycomb). Android 4 (Ice Cream Sandwich) merged the phone ability of the 2.x branch with the tablet ability of the 3.x branch - 4.0 was the first Android version which officially supported phone and tablet.
