I downloaded the upgrade on 06/01/2013 and I am also having data issues. I am having the hardest time connecting to 4G LTE, even worse my data drops off the face of the earth completely now. I have made sure my network setting are correct as well as taking out the sim card, but it has not helped. Today I went into a Verizon Wireless store and the very nice man checked it all out, but it did not help. This is extremely frustrating considering I have had my phone for such a long time and have not had one single issue until now with this "new" update. I wish I would have just left it alone and I would be having these issues. Any advise? Do I need a new sim card or is it something that Verizon needs to fix internally.
Thanks!
