So the next version of iPhone was finally announced on the 10th of September. Apple's marketing strategy seems to be about repackaging existing technology in a way that entice people to buy their products. In the previous iPhones there was a big push on Siri, the voice control function. It wasn't something you need for a phone but Apple made users think its a useful function your phone should have, I doubt many people use Siri after they have bought an iPhone.
Now comes fingerprint sensor to unlock your phone, not something you need but it certainly is a useful addition. Personally I'm looking forward to experimenting with 2 camera functions, the burst mode and slow motion videos, here is a clip about these new features...
