Having problem with the wifi signal on my phone. My router is only 1 room away from me but i only get 1 bar of wifi signal and sometimes my phone won't even read the router. Router has been in the same place as always and i used to be able to get full reception in my room. Both my iTouch 3g and MBP are able to get full bars, its just my iPhone thats having an issue. Anyone know what might be the problem? I didn't buy apple care and i bought the phone on release day, so I'm not sure if apple will fix/replace my phone if this is a hardware issue.
