  • Will you get additional charges for using iPhone hotspot? I was looking around threw my settings on my iPhone today and I saw hotspot. So I looked at it and figured it out and everything but my question is if you use the hotspot will you get additional charges? Even if you don't go over your monthy data limit?
  • What additional cost may occur from making my iphone a personal hotspot? I turned on the personal hotspot option in settings on my iphone but it says additional costs may occur. Does that mean it costs money for me to connect my other devices or just if i exceed the amount of 3g i'm paying for.
  • Stolen Iphone, what to do with accounts on there like Email? So my iPhone was stolen today (had a pass code) but if they did get into the phone is there a way I can stop them from getting into my Hotmail as I use my Hotmail on my mobile as well as Facebook, but I took my number of Facebook and stopped active sessions on there.
  • Iphone 5 or 5s (read additional details)? I currently own a galaxy s4 but can't stand the phone and want to upgrade to either a 5 or 5s. I can use my att upgrade to get the 5s 32 gb for 299 or can get a 5 on ebay for around 430ish give or take. What is the better choice? Only problem i have with upgrading is that i will be stuck for 2 years and won't be able to potentially get the iphone 6
