The best smart phone operation system. actually, to call somethings the best sometimes always lead to the controversy. In this case, we are talking about what is the best smart phone operation system. For me, it depends what purpose they serve, and in this particular case, i think i phone4 is the best smart phone operation system because of its functions. Here, this is its spec. Size and weight1 Height: 4.5 inches (115.2 mm) Width: 2.31 inches (58.6 mm) Depth: 0.37 inch (9.3 mm) Weight: 4.8 ounces (137 grams) First is because of its size.

For the information I mentioned above the size of this is not the smallest smart phone, but for me I think its size is very suitable for carrying as this device is used as portable device.

Capacity3 	16GB or 32GB flash drive Now we are talking about its memory or the capacity. It provides 16gb and 32 gb depend on the one u pick. This size of capacity may not be seen as large as the cpu or computer memory, but if compare with its size, this much of memory is very Hugh. Either 16gb or 32 gb is too much enough to proceed the tasks in day. You can keep like 5 dvd movies for 16gb and 10dvd movies for 32gb Display 	Retina display 	3.5-inch (diagonal) widescreen Multi-Touch display 	960-by-640-pixel resolution at 326 ppi 	800:1 contrast ratio (typical) 	500 cd/m2 max brightness (typical) 	Fingerprint-resistant oleophobic coating on front and back 	Support for display of multiple languages and characters simultaneously Now we are at one of the most important reasons that inspire me to choose this device as the best smart phone operation system. The screen for iphone4 is in the very appropriate size. It is big and clear. It provides “true color” and its resolution is very good Power and battery2 	Built-in rechargeable lithium-ion battery 	Charging via USB to computer system or power adapter 	Talk time: Up to 7 hours on 3G Up to 14 hours on 2G (GSM model only) 	Standby time: Up to 300 hours 	Internet use: Up to 6 hours on 3G Up to 10 hours on Wi-Fi 	Video playback: Up to 10 hours 	Audio playback: Up to 40 hours

In every day, we have to use this thing a lot, so battery is very essential as it is the main thing that runs this device. 7 hour for 3g 14 hour on 2g internet use up to 3-10 hour depends on using 2g or 3g. 10 hour for video, and 40hour for audio. It totally touches my standard of the device I really want. It satisfies me so much because of the long live bettery. Audio playback 	Frequency response: 20Hz to 20,000Hz 	Audio formats supported: AAC (8 to 320 Kbps), Protected AAC (from iTunes Store), HE-AAC, MP3 (8 to 320 Kbps), MP3 VBR, Audible (formats 2, 3, 4, Audible Enhanced Audio, AAX, and AAX+), Apple Lossless, AIFF, and WAV TV and video 	Video formats supported: H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format 	Support for 1024 by 768 pixels with Apple VGA Adapter; 576p and 480p with Apple Component AV Cable; 576i and 480i with Apple Composite AV Cable (cables sold separately) It also serves many types of files

Camera, photos, and video 	Video recording, HD (720p) up to 30 frames per second with audio 	5-megapixel still camera 	VGA-quality photos and video at up to 30 frames per second with the front camera 	Tap to focus video or still images 	LED flash 	Photo and video geotagging

Even though the camera provided in this smart phone is not the best in terms of pixel, I think it is enough for me that you can take picture in the high pixel up to 5 megapixel, and it also has LED flash. In conclusion, to say that what is the best is depended on what is the purpose we expect them to serve us. And in this case, as I explained many reasons above, it is clearly that iphone 4 satisfies me in many purposes. Although its price is not very cheap, I am willing to pay for it.
