Apple’s official specs on the iPhone 4 state that it can run H.264 video up to 720p at 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160Kbps, 48kHz, stereo audio in .m4v, .mp4 and .mov file formats. However if you remember back a few months it was shown that the 3GS could playback 720p/1080i video, although it was not officially supported, see related for the link. So this has made me think that due to the bump in CPU power, now that the iPhone is running Apple’s A4 chip that it should be able to playback full 1080p video.
With the extended battery and retina display, I can imagine that watching HD video on the iPhone 4 will be stunning but I can understand why Apple doesn’t include it official as it does save battery life playing 720p instead of full 1080p.
Also if you plug your iPhone 4 into your TV it would be a useful device to watch HD movies without the need for BluRay.

Similar to AT&T in the US, O2 has now put a data limit on pay monthly users. O2 had already put a 750MB limit of Pay As You Go users but have now changed there unlimited plans to have limited data caps. The cost for additional data isn’t that steap and for those who need it shouldn’t be that much of an issue but it opens up a competitive advantage to any of the multiple UK carriers who offer true unlimited data.
It began with O2 exclusivity but now most of the major UK carriers sell the iPhone, Three has just been added to that list of carriers which is an intresting move. Three usually offer very good deals and make the devices very cheap so we could possibly see a cheaper iPhone 4 from Three.
All the carries have confirmed that they will be selling the iPhone 4 from June 24th so it’s going to be an interesting launch and a strong amount of competition.
