I don't have a whole lot of complaints about the iphone, but this is honestly one of my biggest pet peeves. My iphone will randomly grab wifi networks randomly without me wanting it to. Now that's not too bad... but it will do that even if they don't work. I don't really understand why not all wifi networks work but a lot of the time they will be messed up or have some sort of weird blocks, types, or restrictions.. I dunno. But what I DO know is that sometimes I try to access the internet, or my maps, or some internet using app, and i CAN'T use it because of some bogus wifi network my iphone decided to connect to!! So after I realize what has happened i have to go and turn off wifi before I can do anything... a little frusterating... Has anyone else experienced this?
