When you are trying to update or restore your iPhone or iPod touch with iTunes, the update or restore process may stop, and you may see an alert message in iTunes. You may also see the "Connect to iTunes" screen on your iPhone or iPod touch:

The alert message in iTunes may also include one of the following numbers (but is not limited to): 2, 4, 5, 6, 9, 13, 14, -18, 19, 20, 21, 23, 28, -48, -50, 1002, 1011, 1013, 1015, 1601, 1602, 1603, 1604, 1608, 1609, 1611, 1612, 1639, 2009, 3004, 3013, 3014, 3015, 9807, -9808, 9844.

You can view your MobileMe Gallery and quickly access your friends’ galleries with the Gallery app for iPhone and iPod touch. For help using the Gallery app, open the app, tap Settings in the upper-left corner, and then tap Gallery Help.
If you encounter issues while using the Gallery app, the steps below can help you troubleshoot further.

As with any application downloaded from the App Store, you can safely remove the Gallery app from your iPhone or iPod touch.

When you arrange your albums at me.com/gallery, you may notice that they are randomly rearranged after you log out and then log in to MobileMe. This reordering is not reflected anywhere else, such as at gallery.me.com/membername, on your iPhone, and in iPhoto; each program, device, and application displays photos, movies, and/or albums in a different random order. 
Also, when you upload multiple photos or movies to an album at me.com (either at gallery.me.com/membername or me.com/gallery), they are posted in a random order.

Customers with multiple email aliases defined in Exchange will see all of their aliases listed in the From field if they tap the From field when composing a message:

Note, however, that although customers can select a different alias from the list, only the default alias is used for messages sent via Exchange.
