Specifications from the Samsung website:
In January 2007 Research In Motion, creators of the BlackBerry handhelds, filed suit in United States federal court claiming the BlackJack trademark was too similar to the BlackBerry mark. They alleged that Samsung had named their smartphone with a word beginning with "Black" just to mislead the customers that would come to the cellphone stores with the intention to purchase a BlackBerry. A month later the two parties settled out of court. In January 2008, Rogers Wireless and Fido Solutions released the Blackjack II in Canada under the name Jack.
For handsets manufactured between November 2006 and February 2007, there is a known defect in the antenna assembly, causing a large number of dropped calls.
