Mobileme calendar freezing and painfully slow

Question

Both my ipad and iphone4 calendars are painfully slow and freeze up. Switching from month to month now takes about 10-15 seconds while it used to be instantaneous. Anyone know if there is a fix for this.

Answer 1

I have this problem too. My symptoms are that when I open the calendar, the calendar starts, but appears empty. The "network in use" spinning indicator next to the wifi on symbol in the screen header is on. It takes at least 20 seconds and as much as 45 seconds before any calendar entries are displayed. If you try to change the view (e.g., from day to week) or change the date(s) displayed, it also takes a long time to display.
If I had a slow internet connection, I guess I could understand, but I have a 15Mbps down, 5Mbps up FIOS connection which is really fast. I don't think the problem is related to wifi, but I couldn't say for sure.
I don't have this problem on my iPhone 4 (also iOS 4.2.1). It's a tad slower than it used to be, but at least it displays calendar entries within a couple seconds.
When I enter a new appointment, the same thing happens--after I hit done, the entry doesn't appear for many seconds after the appointment entry form has been closed. It's like it has to send it to MobileMe and then download it before it will display it.
On top of all that, the calendar app sometimes crashes, which it never did before.
If this keeps up, I'll have to move to Google calendar, as the very long delays makes the calendar unusable in practice.
