I bought a Nokia N70 a few days ago and an USB cable with it and today I tried to connect it to my PC and I installed it and then installed Nokia PC Suite. It told me to pull the USB cable out and then put it back in.I did that and the PC Suite recognized it for like 10 second.I DID NOT move the phone OR the USB cable.It just said that the connection was interrupted.The I tried again to reconnect it and it also stayed for only 10 second or so.So my question is: why does it do that? Why is my phone staying connected for only 5-10? What is the matter with it? Please help me
