Are the following technologies 3G,Edge, Gprs and Wi-Fi necessary at the same time in mobile phones?
Its not necessary to have all those connections at the same time let alone on the same phone,it all depends on how much time you have on hand for the internet ,some of us have loads of time but do not want to waste on slow connection speeds,wifi is certainly fast but not at all stable whereas gprs is is very stable but immensely slow 3G would certainly do the job at 384 kbs yet stable enough to can label it reliable.
