There’s only hours to go until Steve Jobs takes to the stage at this year’s WWDC in San Francisco.

As usual, there are a lot of rumours and a lot of mystery about what is going to be announced. I’m only certain on a few things, and a lot I’m pretty sure about. The rest, well, the rest are things that ‘would be nice’.

iPhone

First up is what everyone’s been waiting for… A new iPhone. A lot of people have been calling this ‘iPhone 4G’ – Well that certainly isn’t going to happen. Firstly, all networks internationally are yet to agree on what ’4G’ actually is! Sprint (USA) currently have a partial 4G network, but AT&T don’t and the iPhone is still exclusive to AT&T in the US. There currently isn’t a 4G network provider in the UK!

You could call it the G4 as it’s the fourth generation of the iPhone, but I’m pretty certain it’s going to be named iPhone HD - It’s a hunch, but the spec of the screen and camera (for 720p HD recording) indicates this is the way Apple are going.

We’ve all seen the leaks from Gizmodo (who subsequently are actually banned from this year’s WWDC) so I’m not going to bore with repeating the spec but I’m excited about this! I’m certain they’re not gonna release the iPhone tomorrow. So certain that I haven’t started getting my iPhone ready to sell! I expect the iPhone HD to be released on June 22nd but any delays in manufacturing the thing could push it back to late July.

iPhone OS 4.0

Don’t expect to be getting a software update any time tomorrow. The Golden Master version of the beta hasn’t been released to developers (me) yet and this is what will be announced tomorrow. The fourth beta has come in leaps and bounds in stability, and I never have a crash on my iPhone. This final beta will be released to developers tomorrow (so everyone can get their apps ready) and then the 4.0 update will be released when the iPhone HD is out.

Safari 5

Safari 5 is going to be showing it’s face too. With fast loading times, pre-DNS fetching, smarter address bar, ‘private mode’ icon and a new ‘Reader’ mode which is kinda like Readability. I was hoping for the official release of ‘extensions’ as well, but apparantly that’s not gonna happen.

Apple TV

There’s also a fair bit of murmour surrounding Apple’s ‘hobby’ Apple TV. Now I’ve been an Apple TV user for a few years now and I still regularly use it. It’s a shame it can’t do more as I don’t buy that many Movies or TV Episodes from iTunes any more. It’s great as a remote speaker to my iTunes library on my MacBook and watching podcasts is great, but that’s about it.

There’s rumours that it’ll be a new device, running a similar getup as the iPhone OS. Or just an app on the iPhone HD and iPad. Who knows? I hope it’s not a new device, as I like the look of mine and don’t wanna see it go to waste.

MobileMe

Finally, there’s MobileMe. Apple’s premium service which gives you email, calendar, contacts, ‘Find My iPhone’ and a few other features that you can find elsewhere totally free. I let my membership expire a long time ago and the rumour is, it’s gonna be free. There could also be a tier-based membership system which gives more features or access if you pay a small fee.

Will Steve have ‘one more thing’ for us at this morning’s keynote? Or will we just get sales updates and iPhone talk? I’d be happy with just that, it seems that Apple are focusing on their biggest selling devices right now. Mac’s sales aren’t slumping, they just ain’t as high as iPhone OS devices.
