Well after install like many of blackrain and then unlock with blacksnow I to lost wifi capabilities. My wife's and my daughters phone have no issues but mine is basically wifi dead. I have restored the phone to original settings via iTunes, I have reset network settings and even all settings. All of the aforementioned was done several times yet with my phone, bone stock running no jailbreak, still will not find any wifi signals to connect to. Any suggestions???

Nobody has any suggestions? After Black Snow it was working but would lose signal and then come back intermittently but now it is just wifi dead. May just have to bring it back for warranty?

I had an issue like that...my iphone would only connect to open wifi and would constantly drop with closed wifi networks.

if you have restore it to a brand new state, no jailbreak and re-done the jailbreak/unlock process and are still having issues with it, then restore completely, delete all content and settings and take it to apple, if still under warranty.
