Apple announcing the new iPhone 4 was hardly the shock of the century, but Steve Jobs still offered up a few little extra morsels to keep all the hordes of Apple upgraders happy.

Here's the run down of all the key information, so if you want to find out whether this is the new phone for you, then check out all you need to know about the new iPhone 4:

1. HD video recording - and iMovie too

If you were looking for the iPhone to get a better camera, look no further than the recent iPhone 4 announcement - it's got HD video recording at a slick 30fps.

You can tap to focus, share with one click and use the built in video light to make sure you get better movies even if recording at night. We're worried this may mean the end of the 'special' ambience in Paris Hilton's 'special' videos.

You can also edit and manipulate the movies directly from the device, with iMovie now developed for the iPhone OS as well, designed to mimic the desktop version.

However, the new app isn't free - you'll likely have to pay around £3.50 for the privilege.

2. New 5MP camera with LED flash

The iPhone has always has a poor camera and almost wore it proudly as a badge of honour - no more, as the new iPhone 4 is packing a 5MP sensor with LED flash too (although sadly it's the same one as used on the video recorder.

While it's not as headline-grabbing as the ability to record HD video, Apple has put a lot of effort into the iPhone 4's snapping capabilities, keeping the pixel size the same as a 3.2MP camera without skimping on the specs.

This means more photons onto each pixel, which in turn makes a better picture. Has Apple finally cracked what it means to be a mo-pho? (MObile PHOtographer)

3. Retina display - not an eye scanner

The iPhone has traditionally had the same specs year in, year out, and the screen has suffered because of it. The 3.5-inch HVGA display used to be lovely - but now it's ageing as WVGA screens career past it.

However, Jobs announced the new Retina Display at the unveiling of the new iPhone 4, which has a whopping 960 x 640 display resolution, and is handily four times the pixel density (326ppi), meaning easy scaling of applications.

One sad thing is it's 'only' an LCD rather than a gorgeous OLED powering the display, although Jobs things that his IPS technology offers superb colour reproduction and a wide viewing angle that's better than OLED.

The overall message though: this screen is so high-res that it's 'beyond the sweet spot', meaning Apple thinks it can't get much sharper on a screen this size.

4. Video calling makes a comeback with FaceTime

Steve Jobs might need reminding what year it is, with the new addition of FaceTime meaning video calling is seen as his 'One More Thing'.

Yes it's cool to be able to talk to your friends, and cooler to do it via the front or back camera. But we mean it was cool circa 2003, when the technology was already out there over 3G.

Actually, that's another thing: Apple won't be letting you talk on FaceTime when you're out and about, rather only when connected to WiFi can you start chatting with pictures.

This isn't going to change in the near future, at least not until 2011, so we're not sure how popular this feature is actually going to be, especially as it's limited to iPhone 4's only.

5. iPhone 4 release date - UK gets 24 June

The new iPhone 4 is going to be rolled out faster that ever before, with the new handset given a 24 June UK release date.

The iPhone 4 is actually going to be released in five countries at the same time: The UK, US, Japan, Germany and France.

Pre-ordering goes live on 15 June, but The Carphone Warehouse has jumped the gun a little bit and put pre-registration for pre-ordering live from today - perhaps a bit excessive.

AT&T in the US is offering the chance to upgrade early to the iPhone 4 is you're due an upgrade this year, and O2 is 'preparing offers for in-contract customers'... with Vodafone announcing availability too, we're hoping this might be a treat for certain customers.

6. Thinnest smartphone ever

Yes, you heard that right - Apple has managed to make its iPhone so thin its parents are starting to get worried.

At 9.6mm thin, it's certainly pocket-friendly, and that's not where the redesign ends either - it's all glass and stainless steel here now.

The glass is apparently to help combat scratches and improve optical clarity, and the stainless steel makes it extra tough - impressive in such a thin frame.

It has integrated antennas that are "part of the primary structural elements of the phone" which means less space, more stuff in there.
