We posted about a new Cydia Tweak called H1Siri that allows you to install Siri on iPhone 4 and iPod touch 4G. But as of now, the famous iPhone developer, Chpwn has warned from using it due to illegal issues.While a slight legal violated may not bother many, Chpwn has shown his disappointment that jailbreaking has become about copyright violation.

A SiriProxy hack is needed for H1Siri to work, which connects all devices to a privately owned server which is operated by the development team. The server is not Apple’s and all the Siri traffic is relayed to Apple’s after being diverted through their server. By this you might figure out that it is not just your voice that is sent by Siri to Apple.This means that when you use a proxy to access Siri, you might be sending SMS,emails,location,contacts etc through that server. Apart from that, it may also violate the copyright’s of the fruit company to obtain needed files before porting Siri on non-iPhone 4S devices.

Apart from all this, it’s broken. There have been report the iPhone 4S key that they used has been blocked from using Siri. You must use a special key from a legit iPhone 4S as Apple checks each request coming from the iPhone4S. But the developers used only one, which wasn’t hard for Apple to pick and block with such a huge amount of Siri traffic coming from that single device. While they can use a new key, they can’t just go out and keep on buying iPhones when one gets blocked.

Apart from all these reasons to stay away from Siri, developer Grant Paul has given us a whole insight on how H1Siri works and why this insecure hack is not going to last long. He was one of the two people behind a port of Siri to the iPhone 4 and iPod touch in late October.According to him, Siri users a cryptographic “token” that uniquely identifies an iPhone 4S. The token is generated daily from your iPhone’s 4S serial number and can’t be faked. The hack H1Siri includes funneling Siri requests through a server and then adds a token from an iPhone 4S there. Because of this, all the H1Siri requests and associated data are funneled through CD-Team’s servers. Since Apple issues this token, they can block it at any time and it would not be a surprise if they block H1Siri soon.

What’s next? We recommend you stay away from H1Siri until the developer finds a fix to these issues. If you have already installed H1Siri, you can remove it by going on Cydia and you will be safe.
