ALL, Turned on my phone this AM expecting to read some email since I sync all my email to the phone. Well, there wasn't any!? Look and NO 4G capability showing. So, turned on WIFI and bam, all my email syncs and I read my email. Just stepped outside for a breath of fresh air and checked the phone - still no 4G functionality!? So, what is going on here with my phone? ATT 4G function down or something? Is there something I need to turn on, that somehow got turned off? Phone worked fine yesterday evening, as checked email around 2200 hours.
