Can I still upgrade if I have the Samsung SCH-1535 which is the version for Verizon? There are differences in the hardware.

Finally got it set up on mine. I used Titanium Backup to backup all my apps and system data and had issues after installing this ROM. The issues were due to the differences between 4.1.2 and 4.2.1. I finally figured out just to backup my downloaded apps and data and all’s well now. The ROM does seem snappier, I especially notice they’ve addressed the issue of the dialer and contacts being slow when not loaded into memory. All in all, I’m pretty pleased.
