Am crushed to say the exact thing happened to me this Saturday (19th) after attendance at a 12 hour business conference. I was actively writing in (and saving) my note until 5 pm over the hotel's wifi. My iphone's app is set to only sync over wi-fi as well. This morning, it is only showing my additions up until 10:21 a.m. of that morning. I am a Premium member and am hoping against hope that something can be done to recover the integral data which was taken down. This is the most important event that I have relied on Evernote for re: documentation as in the past I've had no problems. I don't know if this was related to the recent iphone App upgrade but color me extremely angry and disappointed at this point.
