I use my NOKIA 3500c for surfing via GPRS, connecting by bluetooth for long hours like 4-5 hrs continously. When battery drains I plugin charger.Means I use 3 functions at a time: GPRS,Bluetooth,Charging. BTW using AIRCEL unlmtd plan with edge network.....Speed rocks.....Equivalent to a USB netsurfer. So, is there any harm to my mobile's health? Am I degrading life of my mobile.Plz comment.
