Who would have thought such a simple thing would become such a huge phenomenon? In a matter of months, it seems like Twitter has become a household name and “the next big thing”? You know it must be big, even Oprah is on Twitter now. News even broke that Ashton Kutcher beat out CNN to be the first to reach 1 million followers, as reported by PCWorld. Twitter is even being used to report the news, gaining popular exposure earlier this year for being used to document a Denver plane crash.
As an avid Twitter user myself (I have four accounts), it took me a while to find the perfect Twitter client on the iPhone for my needs. After trying out several, the winner, hands-down, turned out to be Tweetie.
Lately, I have been faced with the same dilemma for managing Twitter on the Desktop. There are variations for every workflow, from the simplicity of Twangle and Twitterific, to more full-featured clients that manage several different types of social networks such as Seesmic Desktop and TweetDeck. I’ve been trying them all. A recent favorite is Nambu.
About a week ago from behind a curtain came the announcement from Loren Brichter, developer of Tweetie for the iPhone, that a Desktop client for the Mac was in development. Yesterday, a preview of the new software was showcased in a screencast.
WOW! I expected something good since I am a cheerleader for the iPhone version, but Tweetie for Mac pulls out all the stops. From the features, to the cool, GUI animations, this looks like a real Mac application that is as much fun to watch as to use. I really hope it has multiple account support and hooks into some other social networks, but I already can’t wait for it’s release on Monday to try it out. I may have found my default desktop Twitter app.

Even though Verizon snubbed Apple when iPhone wireless carriers were initially being chosen, Verizon’s chief executive Ivan Seidenberg has now stated that the chances of an iPhone on the company’s network will be improved once 4G technology is in place.
The CEO explained to the Wall Street Journal on Thursday that Apple is ‘more likely’ to want to work with Verizon due to the wider distribution of the 4G standard it will use to supplement, and eventually replace, its 3G network.
Per Seidenberg, Apple was never likely to create an iPhone handset suitable to Verizon’s existing network due to the company’s choice of CDMA standards. While CDMA and its matching EVDO data format are very popular among carriers in North America and are shared with Alltel, Bell, Sprint and Telus (among others), the standards have very little reach outside of the continent. Choosing CDMA may have forced Apple to make a second iPhone model just to accommodate the rest of the world, which has settled on the more popular GSM and HSPA protocols.
This problem disappears with Verizon’s move towards Long Term Evolution (LTE) for 4G. Unlike the artificial split between North America and the rest of the world today, a large number of both domestic and international carriers plan to move to LTE within the next few years, including AT&T and T-Mobile USA.
Seidenberg has claimed that the network may or may not be the sticking point and the discussion remains up for debate. Verizon is believed to have snubbed Apple early on when the handset was initially being developed. Just after the introduction of the first iPhone, the carrier spun its apparent loss by claiming that Apple wanted too much control over sales and service. Observers have also speculated that Verizon objected to being denied a chance to customize the interface and choose which features to allow.

Mac hacker Charlie Miller, a principal security analyst at Independent Security Evaluators and the winner of the the CanSecWest security conference hacking contest two years straight, has detailed his latest find wherein he was able to run shellcode on an iPhone.
According to Macworld UK, it was widely believed by many security researchers that it wasn’t possible to run shellcode on an iPhone. Shellcode is code that can run from a command line, but the iPhone was thought not to allow it for security reasons.
If pulled off correctly, shellcode allows users to perform malicious actions such as gaining access to a users text messages or call history from a remote location.
Earlier versions of the iPhone OS firmware didn’t have many protections to prevent people from tampering with its memory to run other commands, Miller said. But the latest version of the iPhone’s software strengthened the overall security of the phone, Miller said.
In his report, Miller detailed how he was able to trick the iPhone into running code which then enabled shellcode. To pull this off, Miller said he needed to have a working exploit for an iPhone and a means of targeting a vulnerability in the software such as the Safari web browser or the iPhone’s operating system.
Miller said he doesn’t have one now but stated that if someone did, “this would allow you to run whatever code you want,” Miller said in an interview after his presentation.
In 2007 Miller and some of his colleagues did find a vulnerability in mobile Safari that would allow an attacker to control the iPhone. Apple was immediately notified and later issued a patch for the problem.
Miller said he isn’t sure if Apple is aware of the latest issue and stopped short of calling the problem a vulnerability, saying instead that Apple engineers may have overlooked the issue. Apple also has never come out publicly and said it is impossible to run shellcode on an iPhone, he said.
