Is iPhone 6 still avaliable in stock of apple stores in Brooklyn, USA?

Hey there guys, My Mother is gonna go to USA soon at fountain avenue,brooklyn. So Here, in bangladesh iphone 6 16gb costs $1100 which is quite absurd, This is how people in bangladesh do business. Internationally, preferably in the US, it costs $649 (Starting Price), So i was wondering that I would tell her to bring me one. Im quite unsure that if there is still iphone 6's for sale in the apple stores nearby fountain ave.
I heard all phones were stock out in the first day of realse ( 19.09.14 ). So Yeah, If there are iPhone 6 still avaliable for sale, Please mention the Name of the store, and also the location.

Thank You:D

How to permanently delete old chats on snapchat? (iPhone 4s)?

Whenever I chat with someone in the chat part of snapchat and then go to clear history or delete snaps it'll delete them but the next time I chat with the same person if I scroll up it'll still show all the msges, chats, etc. Anyone know how to permanently delete them? (Don't say go to the tool icon and go to delete snaps or clear history because I do that and it still shows old chats.)

Why do I receive poor wifi signal at my house?

I work out back in my shop not even 100ft away from my house and I cannot hold my wifi connection on my tablet or my iPhone. When I do it's only one bar, very slow, and sometimes it won't find my wifi signal at all. This has become a major problem for me because I work from home and I need my devices to function properly. My phone constantly turns over to use my LTE or 3G network and it's racked up 60+ in overage data charges for at least 6 months now. We just moved here if that makes any difference. Anyway I've called my cable company and they reset the connection and it did nothing, I switched cable company's and still the problem persists. Why this baffles me is because when I search available networks on my phone, my neighbors network has full bars that I could connect to but seeing that I don't have their password to join their connection That doesn't help. But it makes me wonder why I can recive full signal from their wifif and not mine when they are further then me then I am from my wifi box so it makes no sense. If I'm inside my house I get full bars. Any advice would be helpful
