I'm reposting a support email I sent to API support to see if anyone else is facing the same issue:
1. Some users of SimplyTweet (iPhone app) are receiving old versions of the DM timeline. 2. On a related note, I seem to be having the same issue with SimplyTweet's servers (for push notification support) using since_id too, where I get timelines including id < X (note: older) when I set since_id = X This seems to have started these 2 days. I have personally seen issue 1 at least twice on my iPhone (Singapore). As for issue 2, the servers are hosted with Slicehost. Is this a known issue? -- Hwee-Boon
