The iPhone 5, presented today during Apple’s special event at the Yerba Buena Center for the Arts, measures just 7.6 mm thick, 18% thinner than the iPhone 4S.
To accomplish this feat, Apple engineers had to face numerous challenges. One was to further decrease the Micro-SIM, used by the fourth and fifth generations of the 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 engineers more room 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 having gained some design improvements, should also improve the reception of the operators’ signal, Spencer Webb said. 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 more difficult to hold it “wrong”.
As for support for 4G LTE technology, the iPhone 5 should not be compatible with the standard that Brazil will adopt. 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 available speed. 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 the 4G in Brazil, as this technology should not arrive or spread so soon here .
It is also important to warn that those who buy an iPhone abroad will have difficulties to find Nano-SIM cards here. It will not be possible (or at least it will not be easy) to cut the chip to transform it into a Nano-SIM, as many have already done with Micro-SIM, according to the Ubergizmo. The way is to wait for the iPhone 5 to reach the Brazilian lands and / or the operators to start selling the new standard of cards, taking advantage of our * wonderful * 3G connection in the meantime.
Update, by Rafael Fischmann
According to G1, operator Vivo will start selling Nano-SIM chips in Brazil as early as September 15 – yes, this Saturday, even before the iPhone 5’s arrival on the American market.
The price will be the same as for Micro-SIM: R $ 10. Not bad! ?
