So I have an Iphone 4 on version 4.3.3 and have MyWi settings set to Infrasture mode so a device like my PS3 can detect it.
So I tried it and every time I turn on the the wifi switch, it loads with the circle thing and then proceeds to saying cleaning MyWi and just puts the switch put to off.
I changed it to ad-hoc and tried it and it works but the PS3 can't see it but other devices can. Another thing I found and tried was the personal hotspot option built into the firmware which my PS3 did detect(which is a good thing). The only problem with that is that I prefer to have my iphone connected since tethering drains battery and by connecting it to my computer it tethers to that as well.
So basically I would prefer to get this MyWi working and can't seem to figure what my problem is.
