Long story short:
Received my new Q10 this morning (SQN100-2) from Verizon. Made and received phone calls while it was on 10.1.0.23xx and the call went through, no problem. Updated to 10.2.1.1055 and only data works...when I make a call, it says "network error" or "network unavailable". when someone calls me, it just goes to voicemail. Any ideas?
10.2.1.1055 works great on my Z10 STL100-3 :(
