There are some 250 Apple executives in attendance at the Consumer Electronics Show in Las Vegas despite the company having no official presence there.

That's according to a Reuters report that claims even Greg Joswiak, Apple's head of iOS product marketing, has been spotted at the show.

A person "familiar with Apple's plans" apparently revealed to Reuters that more than 250 Apple employees are registered to attend CES, though the company has not officially confirmed this. 

PaidContent also spotted Joswiak at CES, who apparently had his name badge "strategically" covered up to conceal his true identity.

 

As Macworld reported earlier this week, Apple's presence - whether official or not - can be keenly felt at CES with many companies exhibiting products that could only generously be described as tributes to Cupertino's creations.

But however many Apple execs there might be at CES, the company certainly hasn't downed tools, with the release of iOS 5.1 beta 3 on Monday.

CES is not the only trade show in January, however - Macworld | iWorld will take place from 26 to 28 January at the Moscone Center in San Francisco. Of course, Apple doesn't field an official presence at the Macworld Expo any more, and hasn't since 2009, though we're sure you'll still find a few execs checking out the action.
