I've just downloaded the new software for my iPhone and it's BRILLIANT!!
loads of new applications are available that are made by third party organisations and a lot are plain FREE!
so if you have an old iPhone (or the new 3G one- I'm still waiting for mine) then go to iTunes and connect your iPhone and click that SOFTWARE UPDATE button! ![]()
good stuff

If you want an old school look on your iPhone, you might try out the iDial iPhone Retro application called Visua mobile. This third-party application allows you to dial phone numbers via a virtual rotary dial as you see on the picture above
