At last, iPhone3GS has reached our country. Everyone knows this place always launches stuff later than other places, but it is launched here earlier than I expected, by the company that launched iPhone3G package locally, Maxis. Don't worry, iPhone3G is still available. The letter 'S' in for the iPhone3GS basically represents 'speed'. The word 'speed' is used as everything you do on an iPhone3GS is practically 2 times faster than a iPhone3G. It is also more responsive and improved 3D graphics.
iPhone3GS is a lil bit heavier than iPhone3G, though you can say it is insignificant as the difference is only 2 grams. It now offers a bigger capacity of 16GB and 32GB and you can have one more colour to choose from other than the original black colour, white. For user's sake, Apple upgraded the camera to 3MP with autofocus, which is a bit shameful for iPhone3G as it doesn't have one for such a 3-in-1 phone.
Apple added an additional digital compass and voice control into the iPhone3GS too, and prolonged the battery life of the phone. With iPhone3GS, you can now talk +2 hours more than the old iPhone3G in 2G, +3 more hours when using Wi-Fi, +3 hours for video playback and +6 hours for audio playback. Of course these are just approximate and varies from every user.
The other features and specifications for iPhone3GS are basically the same as iPhone3G.You can go and check the iPhone3GS out in Apple's official website. For information about packages offered by Maxis regarding iPhone3GS can be found in the official Maxis webpage.
