Have had my Hero for almost a week now after having BB's in the past and most recently an iPod Touch + dumb phone. Nice to have it all in one device again - much improved from the BBs I must say! In regards to WiFi - is it better to run WiFi where available or get internet off the cell Network? I spend most of the day on a campus that has WiFi throughout so could use that instead of the Sprint network, but not sure what will provide better battery life. Searched the forum, but did not see anything saying one way or the other. On Bluetooth. I have my Hero paired to my car ok, BUT it does not pick up a call right away. I will make a call and the first 15 - 30 seconds will be on my handset and then get transfered to my car Bluetooth. Same happens when answering. Never had this problem with other Bluetooth handsets. Anyone else run into this problem?
