No WiFi after 5.1.1 iPhone OS upgrade
Lost wifi connectivity on 3GS after 5.1.1 OS upgrade. Have tried EVERY remedy, short of wiping my whole phone (have done reboot, backup and restore, reset network settings, reset all settings, etc.). Apple says my "hardware must be broken." Hard to believe, with 350,000 hits with same problem on Google search, just in these few days since upgrade was released. What's the deal? I do not want to wipe my phone and start over (for obvious reasons), nor do I unnecessarily want to purchase a new phone (for even more obvious reasons). Clearly there needs to be a fix from Apple!
