Last month, I jailbreaked my iPhone. I decided after to get back the default config and un-jailbreak my iPhone. Since that, I lost my network signal in my house and I have to go near a window to get it. Before the jailbreak, I catch the signal even in my house.
Could you please help me with that strange problem ?
which signal is weak? Wifi or the cellular signal? if it is the Cell signal it is just a coincidence that it is now weaker or it could be that the cell tower signal is weaker, who knows. I am almost certain it is not related to the JB. I have had times when my GF's 2G receives cell signal when my 3G doesn't very frequently. However my phone seems to see Wifi when hers doesn't.
