NEW YORK ( TheStreet) -- After Amazon ( AMZN) had its moment in the sun last week with the launch of several new Kindle products, this week was all about that other "a" company: Apple ( AAPL). Apple showed off its iPhone 5 on Wednesday, with TheStreetin attendance to live-blog. The iPhone 5 has a 4-inch screen, sets a new thinness standard at 7.6 millimeters, and weighs just 112 grams. The smartphone also comes with Retina Display and runs on 4G or Long Term Evolution (LTE) networks from AT&T ( T), Verizon ( VZ) and Sprint ( S). Other iPhone 5 features include a new custom processor chip, the A6, which is 22% smaller than its predecessor, allowing Apple to save a lot of space inside the phone. TheStreet's James Rogers had positive first impressions of the device, which is set to officially go on sale Sept. 21. > > Bull or Bear?

Every model of the phone was gone within an hour, according to Apple's Web site. Customers can still get their phones through Verizon, AT&T, and Sprint's sites, though sources at Verizon said they were dealing with higher-than-normal online volume, leading to some delays. Shares of Apple traded as high as $696.98 -- near an all-time high -- Friday and rose almost 1.6% on the week to close at $691.28.
