BGR has confirmed with a trusted source that AT&T’s (T) upcoming flagship smartphones for the holidays — besides that flagship smartphone, of course — will be launching on October 21st. This will include the Nokia (NOK) Lumia 920 and the Samsung (005930) Galaxy Note II. An AT&T spokesperson had no comment. Nokia unveiled its flagship Lumia 920 smartphone during a press conference last week, and it features a 4.5-inch display, a unique design and Windows Phone 8. Samsung’s Galaxy Note II was announced ahead of the annual IFA trade show in August, and BGR took a hands-on look at the “phablet” earlier this week. Samsung’s mobile boss JK Shin was recently quoted as saying the Note II will launch in October.
