100 meg in a month, iPhone after a month

Looking at my iPhone I've realized that in less than a month I've used 100MB of data. That is about 30 times the average data usage I had with my N95 and Orange. It does included some app installs, but a lot of those came over home wifi.  I'll admit that my data usage on Orange was capped, but a thirty fold increase surprised me. It does not include much data upload to Flickr, if any. I'm waiting on Flickrexport and haven't tried the others, yet.  Not really news to those of you with iPhones already, but the ease of access to the Internet means those idle moments are used for rss or email or similar. Omnifocus and its syncing to .mac mean I can use the tube ride to process my to do list and it is synced to my mac when I get to work.  I do want my iPhone to be more clever, to know more about me, the activity theory work I've been reading and the aurora video are bleeding across into this post now. Location is only one context, time of day and recency in activity also have a bearing. I'd also like a lot more sites to work on my iPhone, though the rumoured 40 million phones Apple are building might sway that.
