But the lack of an iPhone 5 announcement at WWDC confirms that our deepest fears have been realised, and we won't see the iPhone 5 until the autumn at the earliest, when iOS 5 is scheduled to arrive on our phones.
Apple may benefit from holding off on the iPhone 5, since people on the huge US Verizon network only got a version of the phone that would work on their CDMA wavelength in January. Rushing out an iPhone 5 would have destroyed those sales before they had peaked. Ditto for the newly minted white iPhone 4.
We may even have to wait until 2012 for the iPhone 5. Rumours abound that a modestly improved iPhone 4S could come out before a major upgrade.
Whether it's called the iPhone 4S or the iPhone 5, Apple is likely to want to push a new iPhone out before Christmas.
We expect the next iPhone to get a brain boost from an Apple A5 dual-core processor, like the one in the iPad 2. We could also see a slightly larger screen and the ability to make contactless payments thanks to the addition of NFC (near field communications).
LTE is already popular in the US, and should be coming to the UK soon. The next iPhone could add this frequency to make downloads and Web surfing even faster. It could also combine GSM and CDMA standards into one phone so that it works on more networks worldwide. iOS 5 didn't come with any mention of new gestures that could indicate a button-less iPhone 5, however.
