i have my first iphone (5C) and noticed in the usage section under storage it says i've got 6GB available, but i've used 7.3GB. what does this mean? i though when you run out of storage, that's it. does this mean my bill is going to be higher or something? question 2: when i bought the phone the salesman said that whereas i have a wireless network at home that i could use that when i'm in the house so i don't run up my bill. he said that if i went to make a call or use the internet via the iphone, that it would prompt me for my wireless network password. it never did. however, i did set up the phone w/my wireless network password. given that i did this and that i've never been prompted for the password, would i be correct in assuming that the iphone automatically jumps on the wireless home network connection when i use it in my home?
