I have a first generation iPhone which I have recently unlocked for v3.14 with pwnage 3.14.  I am having issues with wifi data transfer when connected to my home LAN.  The iPhone appears to be connected to my network in the iPhone's network settings, but the "wifi" icon is not generally displayed on the top left of the screen (it is displays briefly when I turn the unit on, then disappears). 

Any assistance is gratefully accepted.
