Hi all there.. !!

i have an iphone 3g with 4.2.1 jailbroken 6.15 BB. My problem is the WiFi, when i go to settings > WiFi and turn it on, i just get no WLAN in range can be detected, even when i'am sure that i'am just standing side to side with the AP.

That is a problem i couldn't detect is it Hardware or Software related. i tried to downgrade to 4.1, i get the same .. the circle of loading or searching for WLAN just keep circling and nothing can be found.

Please to all helpers out there, can i fix my iPhone WiFi ?? lead me to an answer

You will likely want to downgrade the baseband from 06.15 to 05.13.04. This can be done with redsn0w 0.9.14b1 or newer. The 06.15.00 baseband has been linked to WLAN problems, GPS problems, and battery life issues. It is recommended that you downgrade to restore standard functionality (while still keeping an ultrasn0w capable baseband).
