I am using MFMailComposeViewController to sent email from my App. It takes around 4 seconds to save a draft but the 'Delete Draft' button completes the task instantly.Both options work fine in simulator but not in my Iphone 3GS running on iOS4.1.
I tried a few apps from App store and they also exhibits the same lag while saving the drafts but this is not the case when using iphone's default mail app. Anyone else seeing the same issue? Appreciate if anyone can share a solution or work around.
I'm also on a 3GS, 4.1 and I do not experience the lag you mention. Have you tried a fresh restore of your device or maybe upgrade to 4.2.1?
