iPhone 4S has now debuted with the memories of the late Steve Jobs. This is the first time that an iPhone hits the markets worldwide without Apple's legendary co-founder.

The smartphone, which may or may not live up to consumer's satisfaction with the previous iPhone 5 hypes, had been unveiled just a day before Jobs died. The device evoked strong online pre-orders.

Shoppers had started to queue up outside the Apple retail stores hours before the sales began.

Apple, previously, sold 1 million iPhone 4Ss in the first 24 hours via its Web site and carriers AT&T, Verizon and Sprint, which made its debut this time.

The 3.5-inch TFT Retina multi-touch display device has arrived with a rear 8 MP camera with 1080p HD video capture capability and secondary VGA camera for video chat, and an A5 processor powered by 1GHz dual-core ARM Cortex-A9 CPU, PowerVR SGX543MP2 GPU.

The new 140 grams device also features the new iOS 5 that will arrive with 200 new features that will include Improved Notifications System, News Stand and iMessage. A dual-LED flash camera, however, is missing.
