Although I’m a bit late on this topic, unless you’ve been living under a tech rock for the past two weeks, you would know that the next generation iPhone 4G was found lost in a bar in Redwood City, which somehow got into the hands of Gizmodo. They took a million pictures of it and posted a video of it on their website, and not soon after, the entire globe was talking about it. Apple’s multiple requests for the return of the device didn’t stop Gizmodo, and who doesn’t feel bad for Gray Powell, the Apple software engineer who left the device at the bar, which was disguised to look like an iPhone 3GS. A stranger found it and soon realized it wasn’t a regular iPhone, so he called Apple multiple times trying to return the device, but they didn’t believe him. Gizmodo somehow found out and payed enough money for this person to hand the device over, which would be exploited all over the web. There’s a video of it here.


What is 4G?

4G is a new generation of wireless technology for cellular devices, and it is basically capable of doing everything 3G can, twice as fast. The tree of developing technologies for cell phones is just an upgrade of speed, as 2G was faster than the first generation, and 3G is faster than 2G and so forth. As 4G becomes more and more popular and demanding on today’s smartphones, a proper understanding could definitely help in deciding if you really need it for your next phone. There are different types of 4G, as there were different types of 3G (UMTS, HSDPA and EV-DO). The two main divisions of 4G are WiMax and LTE, but you don’t need to go into the deep technological details of the two.

LTE, which stands for long term evolution, is when the cellular devices transmit everything, even voice, as data. This is a completely new way of receiving and sending data, which is why it’s an “evolution”. Many of the large U.S carriers, including AT&T and Verizon Wireless have announced they will be using LTE for their future 4G technologies, and testing has shown LTE is capable of speeds up to 50mbps.

WiMax, which stands for Worldwide Interoperability for Microwave Access, isn’t considered an “evolution” because it’s way of transmitting data, is very similar to today’s Wi-Fi. WiMax is capable of speeds up to 10mbps, much slower when compared to LTE, which is probably why Sprint is the only carrier in the U.S so far that is supporting WiMax.

Currently though, WiMax has much more of an availability than LTE as it’s still being tested, but by 2011, carriers like AT&T and Verizon Wireless will be introducing 4G phones and 4G coverage all over the map.
