Connectivity? The iPhone 4 makes a number of important jumps here with support for HSDPA and HSUPA as well as 802.11n alongside the existing Bluetooth, EDGE and so forth. 4G? Don't be silly. We didn't get any HDMI/DisplayPort connections, but that shouldn't be a surprise.
Battery life? There's a small, but welcome bump given the higher res screen and faster performance. You'll get up to 7h 3G talk time, 6h 3G browsing, 10h WiFi browsing, 10h video playback, 40h audio playback and 300h on standby. This compares to the 3GS figures of 5h 3G talk time, 5h 3G browsing, 9h WiFi browsing, 10h video playback, 30h audio playback and 300 hours on standby.
Capacities? Here's a surprise: Apple is sticking to 16GB and 32GB models, no 64GBer to be seen. The iPhone 3G is also no more with an 8GB iPhone 3GS replacing it as the base model.
Jobs' traditional 'One More Thing'? This actually harks back to the front facing video camera. Jobs has announced 'FaceTime' - a new core app for full screen video calling which works over WiFi ("we’re working with the cellular providers to get things ready") and automatically switches between front and back cameras, landscape and portrait viewing. It's nice, but not exactly "one more thing" mind blowing.
When can we get it? Pre-orders start 15 June for the UK, US, France, Germany and Japan with a 24 June release date. 18 more countries will get it in July with 88 on the list by September. Only US pricing was mentioned with Jobs saying the 16GB and 32GB models will cost $199 and $299 respectively on a two year AT&T contract and the 3GS dropping to $99. This mimics existing iPhone 3GS/3G price plans in the US so expect telcos in the UK to do the same.
What of iPhone OS 4? Nothing new here other than Apple's curious decision to rename it 'iOS 4' - which will come as something of a shock to Cisco which owns this patent for its 'Internetwork Operating System' which powers its routers and switches and consequently most of the Internet. Then again Cisco also owned the rights to 'iPhone' so I suspect a deal will once more be hammered out.
iOS 4 firmware will launch on 21 June for iPhone 3GS and 3G, Happily iPod touch owners will also get it free with Apple finally not fleecing them with the usual £4.99 upgrade cost. Any other asides? If you're getting an iPhone 4 you'll need a new dock which Apple has said will cost $29 and it is also making its first Apple branded case which it calls the 'bumper' (below) - also for $29. It will come in a variety of colours.
All in all not much of this is revelatory, but there is no denying the iPhone 4 is an extremely impressive and well rounded technological achievement and one which puts it back on top of the smartphone world. At least for now...
