Apple has recently fixed an iPhone security hole which allowed hackers to take control over your iPhone ,read your contacts,calenders.
“Although there is no formal announcement by the company, an update for the iPhone has appeared on users’ computers. The phone can only be protected from the weakness by synchronising it with the owner’s computer; unlike other phones, Apple is not allowing network operators to update the phones “over the air”. However as the update is 230MB in size, that may be seen by owners – and network operators – as a blessing.”

The security hole relates with text messaging as a hacker can run a malicious code from text messaging as the phone has to process the data that comes with them.
A similar flaw was found in Google’s Android oeprating system for mobile phones, but the company says that it has now been fixed through action by the carriers.Microsoft said that it is working on an update for its Windows Mobile operating system – now renamed Windows Phone – and that it will distribute it once it is ready.
