Some iPhone 4S users are finding that when making an outgoing call the phone mutes the handset making it impossible to hear what the person on the other end of the line is saying.

While initially considered to be just a minor issue the fault has now come under the spotlight of theApple support forums with thousands now getting involved in the debate to try and ascertain what exactly is causing the problem. Confirmed on all three US carriers and now being picked up in the UK the fault is believed to be some form of driver issue with iOS 5.

At present there has been no official word from Apple and no official fix, however if users are finding that they're also having problems making calls then general advice has been to try turning the speakerphone on and then off again and also plugging in headphones, of course, these aren't fixes merely ways of getting around the problem.

The battery difference is given in table below :-

Apple�s virtual assistant Siri was supposed change the way we use our mobile phones. Instead of typing and trawling the net to find information for ourselves, Siri aimed to cut all that out by doing the heavy lifting for us. But a few flaws in the make up of the software have caused major concern among the media and customers alike.

Siri has been the subject of several reports concerning a worrying security flaw. At the press of the Home button, a person is able to send texts, emails, make calls and request calendar information without having to unlock the homescreen using a passcode.

That, of course, could prove very costly indeed if someone gets their mitts on your handset.

But the setting isn't a permanent one - users have the option of switching it off by disabling the option to enable Siri at passcode lock - however, Alan Goode, managing director of mobile security firm Goode Intelligence, argues that because this setting was set at default without users' acknowledgement, many iPhone 4S owners would have been unaware of the potential risks they were exposing themselves to.

He said: �We feel that this option should have been the default option that Apple should have configured on all devices and then let the user decide whether they want to take the risk of someone accessing text, call and appointment services without entering the correct passcode.�

When the iPhone 4S first launched last month, users took to Twitter and forums to vent their frustration at Apple�s virtual assistant application, Siri, claiming that it didn�t work. When asking a question, users were greeted with an error message informing them that the app �cannot connect to the network."

Several outlets have reported that the issue can be fixed by first turning Siri off in the settings menu, then going to Settings > General > Reset > Reset All Settings. T3 did this and found that although it reduces the frequency of the problem, it doesn�t solve the problem completely.

It is believed that Apple will fix Siri-related problems in a new software update � hence why it was released in beta � but not much information is available from Apple on this front.
