What $0.40 fee? Average tx size is 682 bytes. At 0.1 mBTC per KB that is $0.08 rounding up to nearest KB (current version) and $0.05 using actual size (planned for future version).
I may have to research this a little more, I sent .00042 to a charity as an example for someone and it charged me .0005 mBTC, not sure my why tx size was so large..it was through my blockchain iphone app so i ended up paying $.40 to send $.32.
Edit: .00092 was taken out, clarifying post
You are correct vabtc: but this is an Apple problem rather than a bitcoin problem.
Piuk, after a lot of hard work, was able to get the Blockchain.info app into the AppStore. Since then, Apple has forced other apps such as Coinbase and Glyph to remove bitcoin-transfer capabilities.
To avoid a "re-review" of the Blockchain.info iPhone app, piuk has decided not to update it and risk having it removed entirely from the AppStore. This means that you and I and all other iPhone users are stuck with bitcoin wallets that default to the very old (and now very expensive) fees of 0.0005 BTC!
The good news is that the situation may have recently changed. Check out http://www.blockchain.com !
Ouch. Thanks for the clarification. That makes sense and I am sure he isn't the only one confused by that behavior.
