More often than not Siri is giving me the "I am sorry, I am having trouble connecting to the network" message. No doubt a lot of folks are playing with their new phones, but as was mentioned in another thread, this is probably going to be a fairly used feature. It's the biggest reason I bought the new phone. If I continue to get this message in a couple of weeks I will be taking this thing back to Verizon.
Hopefully Verizon, or whomever is causing the lack of server space or whatever is needed will get enough capacity to keep this from becoming a regular issue.
