I take no responsibility for fubaring your phone, but I suffered from the no wifi problem once before too. The attached link will take you to a cab file at xda, which when installed on my titan fixed the wifi issues with not recognizing networks or connecting to networks.
Note, it appeared to brick my phone at first, hanging on the boot screen for several minutes. I pulled the battery for a few minutes and then booted back up normally.
Back up your contacts and such first because this may need a hard reset to get phone to boot, just like every modification we do.
tnetw1251-wifi-ics-fix.cab is the name.
