Hi, This just started happening. It happend in two different places that I have connected to via wifi dozens of times before. I connect to WiFi (unsecured)...all is well. I put iPhone to sleep for more than 1 minute. I awake it and it just stays on Edge...Usually after a few seconds it re-connects to WiFi, but it no longer does this. I've restarted my phone and routers and nothing is working... Can anyone help? Thanks!
