I'm just wondering if people are still having data connectivity issues with their tbolt. Half the time I try to open Facebook, gmail and some other apps, the 4G icon disappears and I get a "no data connection" error. I've replaced the SIM and done everything else. I'm trying to convince Verizon to give me and early upgrade because I think it's an issue with the phone, but of course they won't. They want me now to do an hard reset and say it's one of the apps that's causing the problem. I'm so frustrated now and the phone is becoming unusable half the time. Before I do the reset, I wanted to see if others are losing data intermittently as well.
