Since the launch of the iPhone 4S, many users have complained about downtime problems faced with Apple’s new voice assistant Siri. New iPhone 4S customers started posting on Twitter that Siri was proving to be a tough nut to crack, as it was creating several connection and networking problems.

You know that you’ve run into trouble when the display on the screen shows an error saying: “What can I help you with?” followed by “Sorry, I’m having trouble connecting to the network” just below in a conversation mode.

If this has been the issue then you will need to get into Settings > General – from here disable Siri. Next you will need to reboot your iPhone and then again enable Siri via Settings > General. This probably is enough to set this problem right, according to a CNET report.

Siri, on the new iPhone 4S, allows users to send messages, plan meetings, make phone calls, etc., simply by issuing a voice command. Siri, it is reported, understands what you say, knows what you mean and even replies.
