Apple has updated their iPhone hardware and has been adding features to iOS that make complete use of phone’s hardware. The iOS 4.0 release added many features to iPhone and iPod Touch operating system such as folders, wallpaper, multi-task … If you remember that in order to have new features in a mobile phone a few years ago you had to buy a new device, each update of the iPhone is as if we have a new one.
The 4.1 version can be downloaded right now from iTunes and it greatly increases device’s speed. Watch the video below that shows a comparison between two iPhones, one with version 4.0 and another with 4.1:
For those who have jailbroken iPhone, you should upgrade to iOS via iTunes and then use redsn0w to apply the jailbreak (carrier unlock still not available for this firmware version). You can download the redsn0w 0.9.6b1 right from Dev-Team site. RedSn0w even allow enable functions disabled on iPhone 3G: wallpaper, numerical battery display and multitasking.
Just to compare iOS 4.1 speed: it can be 44% faster than iOS 4.0 but it’s 12% slower than 3.1.2. You can check performance graphics conducted by AnandTech staff.
Excelente esse seu post com essa comparação! Às vezes a gente nem tem noção dessas coisas. Se acomoda com o celular que tem ou então troca por outro…
Realmente você tem toda a razão. Eu tenho meu iPhone à bem pouquinho tempo e anda a ver todas as funcionalidades e tudo o que posso fazer, mas posso dizer que é ótimo.
