Connection Errors Reported on Slow Networks (iOS)
When I am on a slow network connection like Edge, I frequently get "Connection errors". What's wrong?
The connection problems your experiencing can be due to any number of things but mostly occur when you are on a slow edge connection. Twitterrific experiences these problems more than other clients because we have a unified timeline which means we fetch ALL of your tweets on refresh - Normal, @ replies, DM's etc. and then combine them into a single stream. When your connection is slow, sometimes this refresh takes longer than twitter allows, times out and connection errors are reported.
The only way to avoid this problem is for us to fetch fewer tweets at a time (something users have told us they hate) or move to a stronger network connection. Once you're on a WiFi or strong 3G network, 99% of the time, these connection errors vanish.
