I have given up on making this phone work with its default setup so I rooted it.
First you will need to download and install the Android SDK from http://developer.android.com/sdk/index.html
. You may need to do a little reading to figure this out.
On the phone you will need to enable USB debugging by going in to settings, applications, development and then marking the USB debugging box.
Connect your phone to the USB port of the computer where you installed the Android SDK and follow the instructions from the developer who determined how to root this phone:

Unzip chaindsdd-su.zip and then get a shell with adb
Set up the dirs, so shell owns them prior to logging. If shell does not own them then we can not control them. If the logs dir already exists, you may have to do a factory reset to remove them. They should not exist unless someone attempted this previously.
Open emode's logset activity. First button should be for enabling log set, enable it. Do not exit the activity, but if you do just repeat the below command.
am start -a android.intent.action.MAIN -n com.zte.emode/.logset
Confirm the log_kernel.txt file exists, if it does not wait a minute and check again.
ls -l /data/local/logs/kernel/log_kernel.txt
If it exists, delete it and immediately symlink it to /data/local.prop, logset may recreate it, if it does delete and try symlinking again.
ln -s /data/local.prop /data/local/logs/kernel/log_kernel.txt
Now we want to wait for /data/local.prop to be created, it may take a minute or two. Keep checking until it exists.
ls -l /data/local.prop
Now once /data/local.prop exists, go back to the logset activity and disable logset. If you don't disable it, it will slowly eat away at all the disk space, and possibly overwrite the local.prop before you get root. Now lets set qemu=1 then reboot.
echo 'ro.kernel.qemu=1' > /data/local.prop
Once you have rebooted, remount, install su.
adb push su /system/xbin/su
adb shell chown 0.0 /system/xbin/su
adb shell chmod 06755 /system/xbin/su
Clean up your mess!
adb shell rm /data/local.prop
adb shell rm -r /data/local/logs
Reboot, install the Superuser app from the market and enjoy
