How to check whether the iphone purchased is original or fake?

I got a mail saying ''an Unlocked for Worldwide GSM Apple iPhone 4S 32GB White. It costs 17000INR… That guy purchased it directly from the manufacturer. They are brand New, Never Opened, Selaed in Box, Original and comes with complete accessories. WARRANTY: It comes with 12 months international warranty and 3 months return policy that can be used at any Apple store or licensed service.NOTE: If you buy 2 units you are going to get 1 free''.So how can I know whether the phone is original or fake? Should I purchase it or not?

Iphone 4s / Nokia lumia 820?

Hi, Am big confuse which one to choose.either 4s or 820? I don't like to go android side. I hate to take mobile model which that will go out date model with in two or three month.So, i don't go for samsang or HTC. I like to be hold unique device when compare to others.So, i choose Ios & Window 8. Here my concern is which one is best? Really, Iphone have a premium quality & proud to hold in my view. But, 1. 4s has 3.5 inch whereas 820 has 4.0 inch. 2. 4s - 512 MB RAM & 820 - 1GB RAM (Its depends on their hardware.then, will you say both will give equal performance?) If not so, then where will be the lack come? E.x game / multitasking issue? (thing is both H/W were different) 3. Both were dual-core.so, not a issue. But 4s has 800mhz whereas 820 has 1Ghz. Again, where will be a lack? Except above things others will be equal i think so. I don't mind about Win 8 Apps. Hope, it will come soon. Finally, My budget is 30k.So, please sort out me from mess.

IPhone with Pre-Paid Sim Card plan?

My whole life I've had an LG Rumor type phone with us cellular. My parents have cheap flip phones. My parents think its bogus to pay a lot for data plans so we don't get them. But my Aunt is sending me an iPhone 4 that I really really want to be able to use. My moms friend moved from Iraq and she uses pre-paid sim-card plans (Smart Mobile).So my mom says she'll let me do that. But we don't know anything about how that works. My Aunts iPhone is a 4 and it was with AT&T, but she got a 5.So is Smart Mobile worth it? I want unlimited everything.

BTW I don't know if the phone is unlocked. So would I have to get it unlocked?

IPhone 5 Charger keeps going on and off?

My Iphone 5 started virating like every few seconds and I wondered why and I found out the lighting symbol in the battery on the top right corner kept going on and off that's why it kept keep vibrating.
