FYI - I installed FOXFI on the DNA... had no problems connecting to my BB-Playbook (yaya I know BB but talk about screens!)
Performance was pretty good..
I actually clicked on the Hotspot included in the DNA and it worked really well. I also switched to a share everything plan. I assume they not include Hotspot for free since if I go over I pay, so why not give people the means to go over their limit?
I believe there are some limitations to this through vZ, being creative one can circumvent
Since I was new to the share everything plan I double checked with vZ and verified all my situations would be covered under the shared data.. one more app to delete (Foxfi)
