Again, 720p is the standard, not 16:9. 16:9 happens to be the ratio of the 720p standard. Don't put the cart before the horse.
Also, notice how they stop at the hundredths? 1136/640 is still 1.77. So while it's not 720p, it is 16:9.
Sigh. 16:9 is standard both by fact and agreement. Further, that A is standard does not support the conclusion that B is not. Cant be bothered to actually type up responses stating obvious things, so here is another wiki-quote:
720p is a progressive HDTV signal format with 720 horizontal lines and an aspect ratio (AR) of 16:9 (1.78:1). All major high definition (HD) TV broadcasting standards include a 720p format which has a resolution of 1280×720, however there are other formats, including HDV Playback and AVCHD for camcorders, which utilize 720p images with the standard HDTV resolution. The number 720 stands for the 720 horizontal scan lines of image display resolution (also known as 720 pixels of vertical resolution), while the letter p stands for progressive scan (i.e. non-interlaced).[1] When broadcast at 60[note 1] frames per second, 720p features the highest temporal (motion) resolution possible under the ATSC and DVB standards. The term assumes a widescreen aspect ratio of 16:9, thus implying a resolution of 1280 × 720 (0.9 megapixels).
16:9 is standard. 16:9 is implied. Thus, there is no need to state the full resolution, as the resolution (within context) is already given by knowing the horizontal lines.

In 1983, the International Telecommunication Union's radio telecommunications sector (ITU-R) set up a working party (IWP11/6) with the aim of setting a single international HDTV standard. One of the thornier issues concerned a suitable frame/field refresh rate, the world already having split into two camps, 25/50 Hz and 30/60 Hz, largely due to the differences in mains frequency. The IWP11/6 working party considered many views and throughout the 1980s served to encourage development in a number of video digital processing areas, not least conversion between the two main frame/field rates using motion vectors, which led to further developments in other areas. While a comprehensive HDTV standard was not in the end established, agreement on the aspect ratio was achieved.
[---]
An aspect ratio of 16:9 was duly agreed upon at the first meeting of the IWP11/6 working party at the BBC's Research and Development establishment in Kingswood Warren. The resulting ITU-R Recommendation ITU-R BT.709-2 ("Rec. 709") includes the 16:9 aspect ratio, a specified colorimetry, and the scan modes 1080i (1,080 actively interlaced lines of resolution) and 1080p (1,080 progressively scanned lines). The British Freeview HD trials used MBAFF, which contains both progressive and interlaced content in the same encoding.
Its okay to be wrong. Its not okay to be a bitch about it.
Edit: i re-read your post. I said the ratio was implied in 720p. You said i was wrong. Now you are trying to make the point that the ratio is implied in 720p? Make up your mind. You cant have it both ways. If theres a problem with not stating the full resolution (your initial position), ratio cannot be implied, standardized, or otherwise given.
P.S. as you can see above, they agreed on ratio before they agreed on resolution. 16:9 TV also appeared long before HDTV.

A) I'll give you the processing, but most material downloaded will most like be sized correctly. (assuming iTunes and handbrake being the most popular sources) Not sure how it affects streaming. And have you ever seen the quality difference on a 56"? (I have on my old Samsung). While noticeable there, it's not enough of a difference to be noticeable on a 4" screen. When the phone is released, feel free to try to prove me wrong by comparing the same content playing on a 720p screen vs the new iPhone.
B) Still have 20/15 vision. Never needed glasses.
Edit: oh, I don't watch videos on my iPhone anyway so I really don't care. Just trying to point out how unimportant these minute details you guys are picking on are.
A) I actually doubt that most material downloaded will be sized correctly. Its a very odd resolution, and little reason to support it. Google wont, thats for sure.
Battery dead. end of post.
