I'm at my wit's end. I've tried all the suggestions found in this forum and others but I'm still not able to join any network. I have an iPad2 64 GB WiFi + 3G. I've had this beauty for over a month and the problem only surfaced now. I've just recently updated the iOS to 4.3.3. It was working fine after the update but then 3 days later it just stopped. Can't connect to any network at all!! I've tried resetting the network settings, restored the iPad to it's factory settings, rebooted my router, renamed my router, all that. I've even spoke to Apple Support and we repeated everything that I've already done but still nothing. Does anyone have any idea how to fix this problem or do I need to bring it back to Apple? Appreciate any input.
