iPhone 4 losing signal when 3g is ON
First, I bought an Iphone 4 GSM. And using it, I noticed that when I turn on the 3g, signal the operator is constantly "no service", "finding service". When they conect in the Edge, they just connects with a very weak signal.
My second problem is that when I use the wifi network, it has a very weak signal reception.
Someone heard a problem like this and how can I solve?
Is this a good question?
