This doesn’t address the root problem, but liberal use of Imageoptim and ImageAlpha can drop file sizes for images by 50-60% in extreme cases. As a web guy when bandwidth matters I’m very familiar with these techniques, but maybe they haven’t got traction in the app world?

When creating iOS apps part of the process of transferring the app resources into the app itself involves compressing the images even further. There are ways to improve this, but at the base line you have it done for you.

Only using XCode’s compression, which isn’t very good. More info at: http://imageoptim.com/tweetbot.html
