Apple has just confirmed that it will hold a US press conference on October 4, a Tuesday. You'd best get saving because we're almost certain this is when the iPhone 5, or 4S, will launch.
It happens just once a year, but is a day sure to get thousands of gadget fans unhealthily excited - iPhone launch day. Unless Apple is planning on a dramatic change of tact, October 4 will be the day the next-gen iPhone is launched. What do we know about it so far? Virtually nothing is certain. As ever, Apple has kept incredibly tight-lipped about its new product, preferring instead to wait until it's ready, like a temperamental artist pulling the velvet cloth off his latest masterpiece.
Looking at the latest movements in tech, the iPad 2 and the writhing soupy mass of rumours that's been simmering since the iPhone 4 launched, it's not hard to make several reliable conclusions. The iPhone 5 will almost certainly feature a dual-core processor, in-line with Android rivals like the Samsung Galaxy S II. The iPhone 4 is snappy, but its 1GHz A4 chip is starting to sound musty - although its performance is admittedly still more than acceptable. This will up its gaming power, and introduce the ability to play high bit-rate 1080p video.
The screen resolution and size will likely stay the same - rumours have suggested that size will rise above 4in, but we think Apple already knows it has hit a certain golden formula with its 3.5in screen. And its 960x640 pixel display remains class-leading with its 329dpi pixel density. If we're wrong, feel free to blow us a raspberry in the comments on October 4.
iOS 5 may be available on October 4 too
One improvement we're almost sure of is in its cameras. The iPhone 4 has among the better mobile phone cameras - it's easy to use, produces decent shots and great video. Yet, at five megapixels its specs are actually way off the best. If Apple continues the quality trend set by the iPhone 4, the iPhone 5's rumoured 8-megapixel camera could be something very special. We'll also be getting the ability to take a snap with a hardware button of some description - for iPhone 4 users the volume button will double for this duty.
Then there's the name. Some say it'll be the iPhone 5, some say it'll be a minor iterative upgrade and will adopt the "3GS-like" iPhone 4S tag. Others even suggest a budget iPhone will be introduced, but we doubt whether Apple would let the base quality of its products drop too low. October 4 should also see the iPhone 4 model drop into the bargain bin (this being Apple, its contents still aren't cheap, mind) so if you're thinking of snapping-up an iPhone 4 this week, wait.
Tim "Tiger Eyes" Cook may present the iPhone 5
This will be the first Apple product launch where tech superhero Steve Jobs has not acted as Apple CEO - having resigned in August 2011. As such, Tim Cook may be the man to take his place in the spotlight. Most likely wearing a shirt, rather than the Jobs trademark black polo neck.
