So lately, seemingly right after the last update, my eris started to only receive texts in bunches and very randomly. Then I wasn't getting phone calls from anyone. I did a hard reset last night on my phone and the problems are sort of better now. Texting still is slow to receive but I get calls. But just now, I tried to make a phone call and I get a message from Verizon saying they cannot authenticate my phone. I call the number they give, and a person did something which they said would fix the problem. That worked for a bit, but its happening again. Should I make the drive out to Verizon and see what's up? The phone is no longer under warranty or anything like that. Thanks.
