For you to eliminate the issue, you have to update your phone. If you have noticed that there are bugs in the Palm Treo 750 operating system, then you may want to update the phone. Palm releases updates for its phones and devices, but you can only get these updates with some providers. If your Palm Treo 700p is provided by Verizon, then you can download a software update. The updating software fully automates your upgrade, so little user interaction is required.

Instructions:

1.Connect your Palm Treo 750 via USB to your computer. Press the "HotSync" button before you update your software. This keeps all your files and contacts up-to-date after the update.

2.Download the Palm Treo 750 update software. (See Resources.)

3.Double-click the ZIP archive. Then double-click the setup file extracted from the archive.

4.Click "Next" throughout the update process. This will take between 10 and 45 minutes, depending on your existing software version.

5.Disconnect your phone when prompted. Dial "*228" (without quotes) and press "2."
