The iPhone 5, presented today during Apple's special event at the Yerba Buena Center for the Arts, measures just 7.6 millimeters in thickness, 18% thinner than the iPhone 4S.
To accomplish this feat, Apple engineers had to face numerous challenges. One was to further reduce the Micro-SIM, used by the fourth and fifth iPhone. The result of this work was the Nano-SIM, which is 44% smaller and even thinner than the Micro-SIM. The new standard gives more space for engineers to increase the battery, which is still the biggest bottleneck for mobile devices.
The fact that the iPhone 5 is longer, in addition to its antenna has gained some design improvements, should also improve the reception of signal from operators, Spencer Webb told MacRumors, antenna specialist and owner of AntennaSys.
Ergonomically, a taller cell means that a normal hand will not be able to cover both antennas. It is harder to hold it "wrong".
As for support for 4G LTE technology, the iPhone 5 should not be compatible with the standard that Brazil adopts. The new smartphone supports LTE (4G) in the frequencies 700b MHz, 700c MHz, 850 MHz, 1800 MHz, 1900 MHz and 2,100 MHz, while Brazil has adopted 2,500 MHz.
Unless the iPhone 5 comes to our country in a new version, supporting our frequency, consumers will not be able to enjoy all the speed available. Although it is available in two GSM versions (A1428 and A1429) and one CDMA (A1429), I bet it will not have an exclusive version for 4G in Brazil, since this technology should not arrive or spread so soon here .
It is also important to warn that anyone who buys an iPhone out there will find it difficult to find Nano-SIM cards here. It will not be possible (or at least not be easy) to also cut the chip to transform it into a Nano-SIM, just as many have already done with Micro-SIM, according to Ubergizmo. The way to wait for the iPhone 5 to reach Brazilian lands and / or operators to start selling the new card standard, taking advantage of our * wonderful * 3G connection in the meantime.
Update, by Rafael Fischmann
According to G1, operator Vivo starts selling Nano-SIM chips in Brazil on September 15, yes, this Saturday, even before the arrival of the iPhone 5 to the American market.
The price will be the same as for Micro-SIM: R $ 10. Not bad!
