New Skype 2.0 app for the iPhone allows voice calls over 3G

Plenty of other VoIP apps have managed to work in this functionality since Apple / AT&T started allowing it last year , but the official Skype app has been a notable holdout. Now, two months after Skype started doing 3G calls on Android with Verizon , there's a 2.0 version of the app for iPhone that brings voice calls over 3G at last. Mobile iPhone calls are free until August, after which you'll need a "mobile subscription." We're testing out the app as we write this and it seems to work about as well any other 3G VoIP app we've tried: passable, not revolutionary.

3G GSM encryption cracked in less than two hours

Looks like all that GSM code-cracking is progressing faster than we thought. Soon after the discovery of the 64-bit A5/1 GSM encryption flaw last month, the geniuses at Israel's Weizmann Institute of Science went ahead and cracked the KASUMI system -- a 128-bit A5/3 algorithm implemented across 3G networks -- in less than two hours

GSM call encryption code cracked, published for the whole world to see

Did you know that the vast majority of calls carried out on the 3.5 billion GSM connections in the world today are protected by a 21-year old 64-bit encryption algorithm? You should now, given that the A5/1 privacy algorithm, devised in 1988, has been deciphered by German computer engineer Karsten Nohl and published as a torrent for fellow code cracking enthusiasts and less benevolent forces to exploit. Worryingly, Karsten and his crew of merry men obtained the binary codes by simple brute force -- they fed enough random strings of numbers in to effectively guess the password.
