There have been reports across the internet of huge problems connected with a recently leaked piece of code developed by some Chinese hackers the “CD-Dev Team.” Currently available in Cydia, iPhone 4 users are being warned against using the hack.
The software for iPhone 4 users, aimed to bring the new iPhone 4S technology – Siri to the handsets. However, in addition to the overwhelming demand for the hack and the crashing of the servers, the software reportedly has other problems.
Not only has the software broken some phones, but it is alleged to also use illegal code. H1Siri involves the use of copyrighted binaries from the iPhone 4S. There are also privacy concerns associated with the hack, as 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."
The H1Siri is reported to have caused a number of problems after installation, including random reboots, camera faults, bricking the phone and causing the handset to stick on the Apple logo.
So if you’re thinking of trying this out – don’t do it! There are some additional Siri experiments going on elsewhere which give access to the dictation functionality offered by Siri, but as of yet, no other hack offered access to the full functionality as H1Siri claimed to do.
