We are living in an era when mobile technology is updated in a striking speed. This probably is because people always expect more fantastic functions of the mobile device even though their current iPhone 4 has already been amazingly spectacular for a person ten years ago.

It only took several months for the iPhone 4 users to expect the new generation of iPhone. Almost everyday you can find a rumor about Apple’s iPhone 5. When will it be released? What features will it have? All kinds of speculation seems to bring our life some fun. The more there are rumors about iPhone 5, the more people want to get it.

However, do not think that the whole world is just waiting for the iPhone 5. Due to the spectacular competitiveness in technology of this century, the user do not lack an alternative device. Samsung Electronics, the world's largest technology company by sales, also boasts its powerful smartphone products. Compared to Apple’s iPhone 5, the rival’s trump card is the Samsung Galaxy S2 which has been released worldwide since early May 2011. So the question here is: Apple iPhone 5 and Samsung Galaxy S2 - Who will be the Winner?

It seems that Samsung Galaxy S2 is in a relatively week position when we look at the sales volume of the predecessors of the two competitors. According to AFP, Galaxy S, the predecessor of the Galaxy S2, sold 14 million units worldwide by April 2011. It is not quite comparable to the iPhone 4, which has been sold 77 million so far, according to Wikipedia. Nevertheless, this does not mean iPhone 5 will definitely be the winner. Although rumors claim it will have many fancy features, we cannot make any conclusion until we see its specification.

On the other side, Samsung has just gone ahead and announced that they have broken the 10 million sales barrier record. The number doubles their previously announced 5 million back in July. The Samsung Galaxy S2 features a dual-core processor, a 4.3-inch (or 4.5) Super AMOLED Plus display, 1080p HD video recording, 1GB RAM, 16GB or 32GB storage options (plus microSD up to 32GB), a GPS, Wifi b/g/n, 8-megapixel rear-facing camera, 2-megapixel front-facing camera for video chat, USB 2.0, 1650mAh (or 1900mAh) battery and Android 2.3 Gingerbread with Touchwiz 4.0 UI.

What do you think? Who will be the real winner between iPhone 5 and Samsung Galaxy S2?
