Newsstand for iPhone download stacks of data?
Sent to the Newsstand developers:
I noticed a large spike in my iPhone data usage, and on investigation I find my recently purchased copy of Newsstand is transferring about 5MB during every refresh of my feeds from Google Reader, even though only one or two new messages are downloaded.
When I sniffed the traffic, I find Newsstand is passing the parameters "?n=25&ck=535895056" to each feed on Google Reader, which downloads a heap of data every time. For example, "GET /reader/atom/feed/http://feeds.feedburner.com/WhereTheHellWasI?n=25&ck=535907056 HTTP/1.1" returns over 225KB of data.
I don't know alot about Atom, but shouldn't Newsstand be passing the "r=o" and "ot" parameters as well, to only get the posts since the last check?
If Newsstand has to download the last 25 message from everyone of my feeds, every time I want to check for new posts, it's useless to me. That's why I'm hoping I've missed something!
