Jailbreaking fans should keep their curiosity away from a new hack that seems to be popular on Cydia at the moment, which is said to port Siri on your iPhone 4.
Known as H1Siri (or Hi Siri!), the port was developed by a group of Chinese hackers, the "CD-Dev Team", and according to various technology sites and blogs, it is potentially dangerous for iPhones, not to mention illegal.
The hackers posted news about a small test they were conducting of the new port for Siri on Weibo, a Chinese social network similar to Twitter. After a short while, the code was leaked and the situation got out of control with servers being overwhelmed by the huge demand.
In addition to unresponsive servers, there are three or four other reasons to keep away from H1Siri. Firstly, it apparently uses illegal code, which is taken from copyrighted software in the iPhone 4S.
Secondly, it may make information on your iPhone accessible to the makers of the software, as respected iPhone hacker chpwn (aka grant Paul) points out: "if you use a proxy to access Siri, you may be sending your Email, SMS, Calendar, Contacts, Location, etc though that server."
In addition, it can cause various problems on your handset, including: random reboots, messing up the settings and even bricking the phone, according to some reports.
But perhaps most sigificantly of all, as iDownloadBlog discovered, it doesn't appear to work! Whilst it seemed to successfully install the Siri interface with all the options on the iPhone, when asked a question H1Siri was unable to connect to the server, replying each time something like "sorry, I don't have a network connection."
