Just want to post some info about usage that was posted in a Vodafone post ont his site at:http://forums.appleinsider.com/showp...03&postcount=9
for your reference:
In this test, I'm focusing on the data use from normal web browsing.
I only ran the test on randomly-choosen *subpages* of the websites AKA NOT THE LONG AND GRAPHIC HEAVY FRONT PAGES, and the chosen sub-pages usually consisted of an article page or forum page, and most had zero flash elements. Just look at how large the average page size is for these popular websites I go to:
engadget.com (blog post subpage) 420KB
yahoo.com (news article subpage) 585KB
nytimes.com (news article subpage) 345KB
seedmagazine.com (article subpage) 223KB
discovermagazine.com (article subpage) 731KB
livescience.com (article subpage) 438KB
tgdaily.com (article subpage) 253KB
technologyreview.com (article subpage) 247KB
macrumors.com (forum page) 217KB
tmz.com (blog post subpage) 433KB
Average sub-page data size: 389KB/page.
So, using an iPhone with different 3G browsing limits, you can view:
100MB /30 = 3.3 MB per day = 8 web page views per day
250MB /30 = 8.3 MB per day = 21 web page views per day
300MB /30 = 10 MB per day = 25 web page views per day
600MB /30 = 20 MB per day = 51 web page views per day
1.0 GB /30 = 33.3 MB per day = 85 web page views per day
5.0 GB /30 = 166.7 MB per day = 428 web page views per day
Think of how fast you can zip through different webpages with a 3G phone getting 600-1200 kbps. You could easily view the 21 pages per day of the 250MB/month data plan in 10 minutes!
And remember, this doesn't even include all the other things people will be doing that use data:
* Google Maps (especially now with GPS!) - Very easy to use many MBs in one quick session of scrolling around a map. Have a route-following GPS navigation for 15 minutes could easily use 25MB.
* Sending and Receiving Email and attachments - Remember, No MMS for pictures! Other office-type and PDF documents will be sent around as well.
* Uploading Photos - Flickr, MobileMe etc.
* Online Chat via AIM/MSN/SKYPE
* Viewing Youtube, MMS-type video, and other online video - video can quickly use A LOT of bandwidth. 3-7 seconds per MB.
* Downloading applications and games
* Online multiplayer gaming
* Internet radio streaming
* Downloading music and video
Not to even mention all the native applications that will require internet access and server access to function....
I hope that many of these countries are able to get a better allotment of data usage on their plans in the future. I'm sure all the telecom companies just aren't used to hardly any data being used on their networks so they've kept prices high. Hopefully that will change with the iPhone and they'll realize how popular data usage will be and lower the rates as the volume of users using data increases.
