im surprised at&t has been responding quickly. I emailed the guy back and said I've called customer support and technical support and a they can suggest is to buy a new phone. So I received another email from another person.
Thank you for taking the time to e-mail AT&T regarding updating the software on your Samsung Focus to Windows 7.5. My name is Gary Robertson, and I am happy to help you with your inquiry.
I have verified the software updates for the Samsung Focus have been available since 6/27/2012. To complete the update please follow the instructions below.
The device update process:
1. Download Zune or WP7 Connector software to PC or MAC (if not previously installed).
2. Connect the device to the PC or MAC.
3. A full backup of the device is performed.
4. The update is applied to the phone.
5. The phone's data is restored from the earlier backup.
All WP7.5 updates are obtained through the Zune desktop software.
I replied saying I've done that and it says my phone is up to date with os 7720
