德国的朋友们要注意了。
http://support.apple.com/kb/TS4208?viewlocale=en_US
Symptoms
Due to recent patent litigation by Motorola Mobility, iCloud and MobileMe
users are currently unable to have iCloud and MobileMe email pushed to their
iOS devices while located within the borders of Germany.
Affected customers will still receive iCloud and MobileMe email, but new
messages will be downloaded to their devices when the Mail app is opened, or
when their device periodically fetches new messages as configured in iOS
Settings. Push email service on desktop computers, laptop computers, and the
web is unaffected, as is service from other providers such as Microsoft
Exchange ActiveSync.
Apple believes Motorola's patent is invalid and is appealing the decision.
Resolution
If you are located inside Germany, and your iCloud or MobileMe push email
delivery has been disabled, you can still configure your iPhone, iPad, or
iPod touch to automatically download new mail in the background by following
the directions below.
For iCloud Mail:
From the Home screen, tap Settings > Mail, Contacts, Calendars
Tap Fetch New Data
Select a time interval for Fetch
Push can remain turned on to continue push service for Contacts and
Calendars.
With these settings, your iCloud Mail account will fetch new messages at
your set interval while you are inside Germany. Push email service will
continue to be available outside of Germany.
For MobileMe Mail:
From the Home screen, tap Settings > Mail, Contacts, Calendars
Tap Fetch New Data
Select a time interval for Fetch
Tap Advanced
Tap a MobileMe account in your account list
Change Select Schedule to Fetch
Tap Advanced to return to the prior screen
Repeat steps 5-7 for each MobileMe account on your device.
IMPORTANT NOTES: Disabling Push for a MobileMe account will also apply to
the Contacts and Calendars service associated with that account. To maintain
push service for Contacts and Calendars, leave Select Schedule set to Push
and continue to check email manually.
Once a MobileMe user has accessed their MobileMe Mail account from Germany,
push email will be disabled indefinitely. Unlike iCloud Mail accounts, push
will not be automatically re-enabled upon leaving the country. Users can
move their MobileMe accounts to iCloud to re-enable push services outside of
Germany.

写的照写, 删的照删. 删完了, 如果还没写完, ls已经看不到了, 但是尚能通过/proc/
xxx/fd找回来. 等写的那方也close了, 至少在文件系统层面就彻底没了.
