Since there is now way to turn off 3g on the iphone 4s. I can compare it to wi-fi... safari is pretty fast and opens quickly, but on 3g (no on wi-fi) it does not even open, even with 5 full bars showing. I tried speed test and with wi-fi 27 ping with 3g again full bars it shows 20% in the ping status and does not even give me a ping number.....its like taking forever. Not to mention that siri does not work... I am worried if there is something wrong my phone...or this is something others are facing.
