I have a BB Tour as my work connectivity, and an air card for my laptop (why they cant tether the BB I dont know). They are both on Verizon. Ive noticed for a long time now that when the signal is strong, they both show the same. When the signal is weak, the air card shows it as weak, and the BB shows it far stronger, like a few bars better or even a different service level (like 1XEV vs 1X). I know the service is slow because email pushes and loading attachments on the BB is slow, and the air card often shows "National Access", not "Broadband". What gives? Is BB overstating service levels? Wasnt this an issue with Apple a few years back? It is quite annoying.
