i just installed a new wireless router in my house and its functioning fine on both my mac and pc computers and my sisters iphone 3g but my original iphone is not picking up the signal. it will either not pick up the network at all or it will locate it but not be able to connect to it. i am completely clueless as to why this is happening. i tried restarting the phone, updating/resyncing the phone, i have no idea. help.
