I jailbreak and unlock my iphone 3g fw 2.1 by Quickpwn2.2-1 and unlock with Yellowsn0w 0.96. I can use it without problem for 3 days after that my Wifi have some problem and now I can't find wifi signal anymore. What should I do?
PS: my router have no problem, I tried it with my notebook, it showed full wifi signal. Thanks
