Finally, I upgraded my 2g iphone to 3gs. before I upgraded to new 3GS, I was a little skeptical about 3GS because I was happy about everything for the first generation. now I felt much better with 3GS ^__^ anyway, I am considering to buy GPS software and need some help. I narrowed down to two GPS software. copilot and Mobilenavigator. I really like the price of copilot but I don't like $20 monthly fee for real time traffic. Mobilenavigator is expensive but looks like very well made software and one time fee of real time traffic. I think I need to know pros and cons for both products before I buy GPS app. Can anyone give any input on both software??
