This wireless data exchange concept is very similar to a few designs we’ve seen already, but Postmachina is going to be manufacturing a wireless device called Project E that holds your personal information and swaps it when it comes into contact with another, similar device. In essence, it can hold all the info on your business card, plus other data (maybe even social networking information) and transfer it to other people you meet at trade shows or other events.

After doing tests with Bluetooth, Postmachina’s director, Renato Valdes Olmos, decided to make their own set of wireless protocols in order to swap information—which can then be synced with a computer and imported into various social networking sites like LinkedIn or Twitter. If this Project E can be made robust and foolproof that it will work without even thinking about it, we could see a huge market for it everywhere. But if Postmachina can take this tech and insert it into cellphones, something people already carry on them, that would be a revolution.

Since the 1980s, cities like Guiyu, China, have been taking in electronic waste from other countries for dismantlement and processing. It’s great for other countries, but takes a huge toll on the people managing the effort because of the “metal extraction of circuit boards” and “open dumping of waste and ash residue into open water”. It’s made the well water and ground water of Guiyu undrinkable, and has to be trucked in from other villages. The lead poisoning level in children is 69%.

After some delays, the iPhone Pwnage tool—which is used to flash your iPhone with hacked firmware that will allow you to run any application, use it unlocked in any compatible cellphone network, and basically do whatever you want do to with it, is now available for download. I have been testing this and previous versions for a few weeks now and it works well, but you will need a 2.0 version of the iPhone firmware to try the latest and greatest.

Pwnage is extremely simple to use. First you have to back up your iPhone data using iTunes.

Then, connect the iPhone, select the firmware from your hard drive and iPwn the iPhone. Pwnage will upload the new firmware to the iPhone and that’s that: the tool will take care of everything and, in a few minutes, your iPhone will be ready to go.

I tried this with the latest modified version of iPhone firmware update 1.2.0 and it works as good as with the previous version. So go ahead, punks, and make Steve’s day.

Note: if by any chance you come across a pwned version of the latest 2.0 firmware, my advice is to use this version, as this Apple beta is not as stable as I wish. Instead, use the previous beta, which worked perfectly.

Sony Ericsson may not be good at delivering promised goods in a timely manner, but when it does finally deliver something—say, its first HSDPA phone for the US market—it does it with style and a shockingly low price. The Z750a is hitting AT&T for just $50 (after a $100 mail-in rebate that you damn well better fill out). The clamshell with the signature-Sony OLED see-through exterior will come in three colors: Mysterious Purple, Phantom Grey and Rose Pink. US availability details and bonus pic after the jump.

Sony Ericsson Blends Style, Sophistication and Speed with New Z750a Clamshell 

New Mobile Broadband Handset Available in the U.S. Only from AT&T
RALEIGH, N.C. —(Business Wire)— Mar. 31, 2008 Mobile phone owners no longer have to decide between high performance and attractive design when choosing a new handset with the new Sony Ericsson Z750a. Available in the U.S. exclusively at AT&T, the Z750a is an affordable and stylish handset with a mirrored clamshell design and a hidden exterior display that illuminates when the phone is in use. As Sony Ericsson’s first 3G/HSDPA handset for the U.S. market, the Z750a features mobile broadband for a high-speed Internet(1)connection and access to multimedia content that complements its multimedia player, 2.0 megapixel camera, Internet(1) browser and e-mail(2) capability using AT&T’s Mobile Email application.

“Sony Ericsson continues to expand its North American portfolio with a distinctive and signature design that combines entertainment, style and speed in a sleek device,” said Karen Morris, vice president of marketing for Sony Ericsson North America. “Representing one of our most distinctive and colorful 3G clamshells, the Z750a will appeal to those who want to do more with their phone - share music, high-quality pictures, browse the Internet - and project a sophisticated image all their own. We are delighted that AT&T will offer this device in the U.S. along with the hugely successful W580 Walkman(R) Phone.”

The Z750a works hard, offering features such as data download transfer speeds from 600 to 1400 kbps from AT&T’s High Speed Packet Access (HSPA) 3G network, support for AT&T’s Mobile Email, a 2.0 megapixel camera, full HTML web browsing(1) capabilities and stereo Bluetooth(R)(3) support (A2DP). The Z750a also plays hard with 3D gaming capabilities, a media player that supports numerous media file types for listening to your favorite music tracks and video. The phone has up to 26MB(4) of internal memory and is Memory Stick Micro(TM) (M2(TM)) compatible - currently upgradeable to 8GB(5) - providing ample storage space for photos, videos, music, games and more.

No matter how smart and powerful the Z750a may be on the inside, it still dares to be sleek and sophisticated on the outside. The Z750a has a reflective mirror clamshell casing and hidden organic light-emitting diode (OLED) reflective display screen on the front of the phone that discretely illuminates when receiving a call, displaying caller identification. When active, it also displays battery life, text message alerts and other useful information. To match anyone’s personal style, the Z750a launches in three tantalizing color choices: Mysterious Purple, Phantom Grey and Rose Pink.

The Sony Ericsson Z750a will be available at AT&T stores and authorized dealers in early April for $49.99 after a $100 mail-in-rebate and new two-year service contract.
