Don't drop TCP connection when I...

The only time connection failure ever poses more than a extremely minor inconvenience is went I am typing large mails, so I just type them in notes and copy/paste them over, problem solved. : D

Oh yeah, that happened to me the other day. Was super annoying...

But can't you just register the app as a VoIP application and use the setKeepAliveTimeout method to maintain your TCP connection for up to 10 minutes? http://developer.apple.com/library/i...mmingguide.pdf

Or you could even use the beginBackgroundTaskWithExpirationHandler method to ensure the connection is not dropped.

Something like this?

UIBackgroundTaskIdentifier hangTight;
hangTight = [[UIApplicationsharedApplication]
          beginBackgroundTaskWithExpirationHandler:^{
              /* if you exceed 10 minutes */
          }];
[[UIApplication sharedApplication] endBackgroundTask:hangTight];

Well? Have you looked into this tactic?
