be sure to thoroughly wipe before flashing... cache, dalvik, system/data, sd-ext (if you use one, and you should)... make sure you have an up to date version of gapps?... you could try wipe>flash rom>reboot, flash gapps>reboot...
virgin mobile network issue. thats an error message from the google accounts app if im not mistaken. your connection is failing. its happening to many users all over the southeast and some mid western states. but to be absolutely sure thats what it is. try another rom or re-download leslies and reinstall it. could have been a borked download of the rom causing issues.
