Apple's iPhone 4S Launch in Pictures

CUPERTINO, Calif. ( TheStreet) -- Apple ( AAPL) did not deliver the much talked-about iPhone 5 at its launch event on Tuesday, with the gadget maker instead unveiling the new iPhone 4S.

A souped-up version of the iPhone 4, the 4S disappointed many Apple zealots who were looking for more fireworks on Tim Cook's first product launch since taking over from Steve Jobs as CEO.

Apple was nonetheless beating the iPhone 4S drum during the launch event at the company's headquarters. In addition to its faster A5 processor, the 4S also contains both GSM and CDMA antennas, which means that the "worldphone" can operate on both U.S. and European networks.

Read on for more information from Apple's launch event:

While the iPhone 5 did not materialize, rumors that Apple was planning to enhance its iPhone camera proved correct. The iPhone 4S boasts an 8-megapixel camera, which, according to Apple, has the "most advanced optics of any phone."

The 4S camera sensor, for example, has 60% more pixels than the iPhone 4 sensor, as well as a new lens, a larger aperture, and an advanced hybrid IR filter. The means sharper, brighter, more accurate images, says Apple.

The tech giant has also built a 1080p HD video camera into the iPhone 4S.

Much of Tuesday's product demo in Cupertino was taken up by "Siri" -- a sophisticated voice tool which can be used to make calls, send text messages and emails, as well as to find directions and a host of other information.

Described as an "intelligent assistant," Apple executives asked Siri questions such as "what's the weather like today?" during the iPhone launch, and received the correct response, to rapturous applause.

Siri can also be used for dictation as well as finding information on, for example, local restaurants, according to Apple.

Apple's iPhone 4S may have grabbed most of the headlines on Tuesday, but the company also made a handful of iPod announcements during its launch event.

These included a new iPod Touch, with iOS 5 and iCloud, priced from $199, and a new iPod Nano with a redesigned user interface, priced from $129.

Features of iOS 5 include iMessage for sending messages between iOS devices and Wi-Fi syncing to iTunes.
