Your Samsung Mesmerize ships with the Android 2.1 operating system, which offers plenty of built-in features but is dated considering Google's updates since then. Fortunately you can upgrade your phone to Android 2.3.4, which updates many elements both practical and cosmetic. Unfortunately, this update does delete all user data, so you should back up all important information before updating.
Download the Samsung Upgrade Tool (see the link in Resources) to your computer, which is required for to update your phone. Double-click the Samsung Upgrade Tool file you just downloaded to install it. You can use the default settings for this installation.
Open the Samsung Simple Upgrade program on your computer. By default a shortcut for this is created on your desktop that you can double-click, but you can also find it by clicking the Start button and typing "Samsung Simple Upgrade" into the search text box.
Click "I accept the terms in the license agreement" and then click "Next," then "Next" again.
Press the Home button on your phone, then press the "Menu" button.
Tap "USB Settings," then "Samsung Kies."
Connect your Mesmerize phone to a free USB port on your computer using the Mesmerize's provided cord.
Click the "Next" button on your computer when it becomes available. It will become available to click once the software recognizes your phone.
Click "Start Software Download" on your computer. This will begin the software update. Do not disconnect the USB cord during this process; disconnection could cause your phone to become permanently unusable.
Wait for the upgrade to complete. Depending on which software version your phone is upgrading from, your phone may restart during the upgrade process.
Click "OK" on your computer when a prompt appears informing you that the update is complete. The phone will restart.
Remove the USB cord from your phone.

You can force a synchronization at this screen by pressing the Menu button and tapping "Sync now."
- You can also back up your phone contacts to your SD card. You do this by viewing your contacts and pressing the Menu button, then tapping "Import/Export," then "Export to SD card" and finally "OK."
