I have just recently got both the CM10 rom on my device along with LTE coverage near me and have an odd issue. I generally have wifi coverage so data isn't a problem, but I noticed once I picked up LTE coverage, if I turn off my wifi, my device says it is still connected to LTE but cannot establish a data session. even if i cycle though connection settings, reboot, etc....
Anyone else seeing this or similar issues
Also, is there anyway to update PRL on a mod?
