Should i get the samsung galaxy s4 mini or iPhone 4S?

I have a Samsung galaxy ace and I love it! My contact is up and I'm not sure what phone to get.

I love Samsung but all my music is on iTunes, also podcasts, and apple has automatic downloads which is so handy! I use my iPod all the time and it would nice to not have to take a phone and an iPod everywhere I go… But I really like Samsung!

Could anyone give me some advice?

Facetime on iphone 5 doesn't work in middle east?

I tried EVERYTHING from going onto restrictions to setting to calling apple to checking everything.
NOTHING ever works. So i installed ios 7 on my old 4S and facetime is there. But i already DID HAVE facetime on it on ios 6.1.3.

SO now i was thinking if i did install ios7 on iphone 5, would facetime get automatically installed on it? Or if i install like ios 5 or ios 6.1.3 on the iphone 5?
Thanks heaps

Added (1). Urgent need of facetime.

btw, i really do need something other than ios7 because i don't like the layout, let alone all its new features. So i was thinking ios 6.0.2 for iphone 5?

Will the iPhone 4 drop in price or stay the same?

We're getting my sister an iPhone 4 since its $450 to have it unlocked since a iPhone 4S and iPhone 5 cost too much to be bought unlocked. She is upgrading big time since her phone is the chocolate 1st gen from Verizon and I wonder since the IPhone 5s is coming out this month will the iPhone 4 drop in price to somewhere lower than $450? And if you know the what's the new price is if it does I would gladly appreciate it.

IPhone not working after being in rice? (water damage)?

I dropped my iPhone 4S in the sink. In a panic I did briefly ring someone, but hung up after 2 rings (The sound was working). I then turned it off, the touch screen etc working fine. I put it in a bag of rice, sucked out the moisture as best I could and put it in the airing cupboard. I left it overnight, and then this morning tried it. For some reason it had turned itself on, and had received texts and facebook messages as usual. Everything worked completely normally, apart from the volume buttons. Also, when playing music the volume slider just wasn't there and it seemed to be on zero volume (I didn't try ringing anyone). I've put it back in the rice and Ill leave it 24 hours. Is this the right thing to do? Can I do anymore?
