Will I get Iphone very cheap?
Will it be cheaper?

Buy Iphone without network contract, buy Iphone it cost a lot of money even it is used.

To but it with contract with a network carrier, it will be cheaper. But I will need to pay for network carrier. What if I sign a network carrier and after 1 month, I quit the contract with network carrier. I would have to pay only for 1 month of network.

But will there be a lot of price to pay to quit the network contract?

Iphone 4s is free with network.
Iphone 5 is very cheap with network.

Added (1). Still would cancellation fee be cheaper?

Why is my sound blocked on my iphone 4?

I can hear music and sound when earphones are plugged in.
I can hear my phone going off
I can hear my tones and stuff.
I can't hear music out loud on speaker.
There's no option to turn up the sound on the part that slides up (on ios7)

Yesterday it had a bit of water damage. My friend fixed it and I just took it off of recovery mode but this is the only thing wrong with it. It's not on mute. I'll fiddle with mute off and on and it will come up as normal but when I go to turn the sound up or down there are no sound bars. It just comes up as ringer. How do I fix this? Do I have to get it repaired professionally?
