3-5??? Well lets see, (1). 1x connection (2). EVDO (3). WIFI (4). Bluetooth (5). infrared, yep makes sense to me. i always have 2 copys running but then again i dont use the BT infrared or wifi. but then again i dont have the problems of the memory leak. When I turn it on I have 19 mg of mem at the end of the day still 19 mg. the only thing I do is I have HTC X Button to close the apps
