We're just hours away from Apple's WWDC keynote speech, and the rumour mill over what kind of iPhone will be released is reaching fever pitch. It's pretty easy to see that a new Apple handset is on its way, but despite some high profile leaks, we're still no closer to understanding what's going to be brought out by Phil Schiller.

TechRadar runs down a few features that Apple has reportedly been looking at for the new iPhone, and rates each one out of ten in terms of likeliness with our soon-to-be famous Jobs-o-meter:

Different flavours of iPhone memory

While there might be a few billion rumours doing the rounds at the moment regarding what's going to be announced on the new iPhone, one of the most vociferous is the notion it will come with an expanded memory set, from a 4GB iPhone 3G for cheap up to a 32GB new version, with 8GB and 16GB thrown in for good measure.

TechRadar's Jobs-o-meter: 8/10

It would be a real shock if we see an iPhone launched in the basic 8GB and 16GB versions again, especially as we've seen some decent information that a 4GB option is on the way and presentation slides of a 4GB version for $99 (around £65).

A new matte black cover

You know Apple, never one to sit back and not make any changes. This year it's going to be big in terms of alteration. We mean BIG. No, not an iPhone Nano. Nor a flip iPhone. Nor a transparent.... look, it's a new matte black cover. What do you mean that's rubbish?

TechRadar's Jobs-o-meter:8/10

We've seen leaked photos of the new iPhone in the same size and shape as before, but this time with a matte black cover. So it's pretty likely. While it might not sound exciting, we're talking black all over, so even the chrome rim has gone. Not only that, but it means you probably won't be dropping your pride and joy all over the place any more... see, not that bad is it?

A fast processor and more RAM

There's a lot of talk that the new iPhone will be announced as the 'fastest iPhone ever' with chat that a processor of up to 800MHz will be stuffed under the cover, with around 256MB RAM to keep up.

TechRadar's Jobs-o-meter:7/10

It certainly makes a lot of sense when you consider that a new iPhone will be rocking the new iPhone 3.0 OS that it would need some more grunt under the hood, and technology doesn't sit still... staying where you are in mobile phone world is moving backwards and all that.

However, we don't think that the processor speed will double, just head slightly north from 400MHZ to around 600MHz.... you know, to keep pace with those damn Palm boys and all that.

A 5MP camera with video recording

Oh, the fun of the iPhone. One of its most idiosyncratic features is the fact it has a camera that, in mobile phone terms, is as good as employing a small child to stand near you with crayon and a pad and drawing what's in front of you when you press a camera button on the device.

But never fear, as the world is starting to believe that the new iPhone will come with an upgraded camera, and some are getting so giddy they're believing it will have a video camera AND a flash, like some sort of Apple ambassador walking round with a pyramid of iPhones and a lady in a posh frock claiming that he is spoiling them.

TechRadar's Jobs-o-meter:5/10

This was a tricky one, because it's probably half right. While we would love to believe the world is about to get an iPhone with a fixed camera, there hasn't been a sniff to suggest a flash will be anywhere near the mix. But thankfully there's a lot to suggest that it will be coming with some video recording software, and who knows, even a better camera and an editing suite too.

Which brings us nicely on to:

The new iPhone will be called the iPhone Video

This is one that popped up recently, which is the sort of time that you'd expect the name to begin leaking out. And it's not just the iPhone Video that's being touted; the iPhone 3GS is also doing the rounds as well.

TechRadar's Jobs-o-meter:10/10

Well, it's 10/10 as in the new phone will have a new name, we just don't know what it is. The iPhone 3GS sounds too un-Apple to be considered, although many believe that's what will turn up (perhaps the 'S' stands for Super, or Speed. Or Steve).

The iPhone Video (think iPod Video, Photo etc) makes a lot of Apple-y sense, but it's not like Jobs' lot to go back in time with style and naming. We've got no idea what the new iPhone will be called, truth be told, but we'd like to believe the Newton MessagePad 3000 is on the cards.

iChat will be enabled via a forward facing camera

Yes, you heard right. iChat on a mobile phone, and with a FORWARD facing camera. OK, so you read it rather than heard it, but big whoop, it's all the same right? Let's be honest, we didn't know how to dress this one up as it's probably the most famous rumour of the lot, so we tried to make it sound exciting with capitals. We failed.

TechRadar's Jobs-o-meter:9/10

This one has real legs, and it pretty much a dead cert to happen, as it marks a logical step forward in the iPhone legacy. iChat would be easily added into from your Apple contacts already locked into you Apple profile, and you'd be quickly up and chatting.

Which leads us to the final rumour:

A special appearance

Shut your eyes and picture the scene. Oh wait, open them, you can't read this else. (If there's someone nearby, shut your eyes and get them to read it to you.)

Schiller finishes the keynote, he's shown off a new iPhone. All well and good, it's called the iPhone Prequel or something, we're all a little underwhelmed to be honest. He lifts it up, and scrolls down to SPJ. Nothing exciting there, you're thinking. We're in the same boat. Heck, we're stifling a yawn.

But then it rings. The big screen fires up. A gaunt-but-healthy looking man's face appears. 'Jobs Residence, Steve on high speaking?'

TechRadar's Jobs-o-meter: 3/10

We can see it now. Apple's stock jumps five percent on the announcement. The world goes crazy despite it not meaning that much. You know how these keynotes go down.

But, we'll be honest, it's a bit unlikely. Unless it happens, in which case we knew it would be coming the whole time.

Of course, there's always the chance that no phone will be unleashed, but hey, that's just crazy, crazy talk.
