AT&T : Does Windows Phone support microSD card for Memory Expansion?
Windows Phone 7 and microSD Cards
Users are strongly encouraged to review this section carefully before inserting the right type of microSD card into Focus, a Windows Phone 7 device.
Windows Phone 7 does not support freely swapping microSD Cards in and out.
Many commercially available retail microSD cards are not approved for use in Windows Phone 7. Use of unapproved cards may cause performance degradation or device instability including unexpected reset and loss of user data. A microSD card class is not an indication of meeting Windows Phone 7 requirements. Approved cards can be obtained from the manufacturer or Mobile Operator.
Once inserted and properly formatted, the memory card becomes an inseparable part of the phone.
A microSD card inserted into a Windows Phone 7 device and integrated into the device's file system is intended to be a permanent modification to the device. Once a microSD card has been integrated into a Windows Phone 7 device's file system, it will no longer be readable or writable on any other devices such as computers, cameras, printers, and so on. This includes an inability to format the microSD card for use in these devices. Improper use (including inserting or removing) of microSD cards on Windows Phone 7 devices may result in one or more of the following:
- System error while powering on the device that prevents the Windows Phone 7 operating system from loading. Note that emergency dialing will function properly.
- Inaccurate reporting of available storage.
- Loss of access to or removal of installed applications.
- Loss of access to or removal of user data/media stored on the microSD card.
- Loss of access to or removal of user data or media stored internally within the Windows Phone 7 device.
- Overall file system performance degradation.
- Device lockup or reset.
Inserting or Removing the Memory Card
To insert or remove a microSD card, you have to reset your phone by using a procedure called a hard reset.
Warning!: A hard reset resets your phone to its factory default settings and wipes all data (pictures, video, contacts, music, and so on) from your phone. Make sure your data is saved to your PC. For more information, refer to “Sync with PC”.
