Nokia's Lumia 920 Sold Out on Black Friday

November 23 may have been known as "Black Friday." But it was a very bright and boisterous day for Nokia

.

According to Trip Chowdhry, the Managing Director of Equity Research at Global Equities Research, Nokia sold out of its flagship phone -- the Lumia 920 -- last Friday. "[The Lumia] 920 Windows 8 Phone on AT&T

, which all but created the smartphone market with the first BlackBerry, has spent the year dragging its feet. Instead of releasing BlackBerry 10 -- the next evolution to its mobile OS -- the company delayed its flagship product till 2013 and chose to focus on

for 2012. Investors still have faith in the firm's performance, however. Over the past three months, RIM shares have jumped nearly 70 percent. Year-to-date, the company is still down more than 25 percent. HTC (2498.TW), another Nokia rival, has had its own set of troubles. In addition to the declining revenue, HTC was reportedly

to release a Windows 8 tablet when the OS launched on October 26. The Taiwan-based enterprise recently lost
