Concerns over the iPhone Perfomance

We at techreview have not had a bad word to say about the apple iPhone, we like many other Australian’s have been wearing apple tinted glasses every since its release in 2007, so much so that we failed to pay real attention to other smart phones brands and their development. Recently Apple released the latest version of their iPhone + iTunes software (OS Firmware 4.0), after a quick glance we found some of the additions to this software to be a great improvement; however ever since updating the firmware we have found a number of issues of phone performance, mainly how sluggish the phone has become. If you have had any issues with your iPhone e.g. slow performance, frozen screens, lost reception then please share your comments and views below.

We are interested to know whether this is a one off or something more.
