Simple question to start off with: 1. Is the iPad 2 GPS using the Cellular Network for GPS? (I think no, but cannot find confirmation (don't confuse with AGPS, this is about GPS only)) 2. Is the GPS antenna and Cellular Network antenna the same, or 2 separate antennas (since GPS only comes with network)? 3. Does the GPS work without a cellular carrier? (I read it does, then I read it does not, which is it?) The not so simple question is: How good is the iPad's GPS? I have read a lot of various reports on the accuracy and speed of the GPS. Of course within a cell network one can use AGPS to better triangulate location, but how good is it in areas of poor cellular coverage? Naturally I expect the size of antenna be a major factor in reception, however I did not see ay GPS antenna. See iFixIt's tear down of iPad 2 for the antennas. (and no, I am not planning to go into jungle with iPad.) Thanks!
