+Mark mail as unread
+===================
+
+There's a somewhat hidden way to mark messages as "unread" in the mail app: When viewing a mail,
+touch the **Details** link in the upper right. Then find the **Mark as unread** link below the subject.
+
+
+Access Network Monitor
+======================
+
+If you like to see the reception status of all the cells you're receiving, type the following code on
+the dialpad and press the dial button: **`*3001#12345#*`**
+
+
+Recover from Recovery Mode loop
+===============================
+
+If you try to update the firmware, you might be stuck in the *"Connect to iTunes"*-recovery mode although you didn't
+change any bit of the firmware (e.g. because of some freakin' errors of iTunes). You now have the choice between a
+long firmware+backup restore - or get your iPhone back running in about 30 seconds. The procedure is described
+at [ihackintosh.com](http://www.ihackintosh.com/2009/09/recover-iphone-3gs-from-apple-logo-or-recovery-mode-loop/). Do
+yourself a favor and **don't try it in Windows**. Installing `libusb` there broke something and after a reboot of
+Windows, all USB devices didn't work and hat yellow exclamation marks in the Windows device manager. Under Linux,
+it's easy as pie. These instructions are for Ubuntu:
+
+  - get [iRecovery](http://github.com/westbaer/irecovery) source code and install [build-essential](apt://build-essential) as well as [libusb-dev](apt://libusb-dev)
+  - compile *iRecovery*
+  - get the iPhone into recovery mode:
+    * switch it completely off, disconnect all cables
+    * hold down the ▢ Home button
+    * keep the button down while connecting it to the PC
+    * wait until the *"Connect to iTunes"* logo appears, then release the ▢ Home button
+  - now run: `./irecovery -s`
+  - wait for the prompt (`]`) and enter the following commands: (if `fsboot` doesn't do anything, type `reboot`)  
+{% highlight text %}
+] setenv auto-boot true
+] saveenv
+] fsboot
+{% endhighlight %}
+  - your iPhone should now boot normally
