Until I swapped to 113 I had the same problem. 109 had issues for me in that i tried to take pictures and they would not save.
113 seems to have fixed that issue , only odd ball bug I had so far with 113 was it thought I had headphones connected and I could not hear any phone calls. After trying every setting I could think of , I finally fixed it by actually plugging in a set of headphones and then unplugging them.
I live outside of the US, so I swapped out the verizon sim card for one of our own, it works fine. If I wanted to upgrade to the v113 of the OS, where would I get it and how would I go about doing the upgrade?
