How much is an iphone 4s in singapore?

In 7 days we will be going to singapore as a tourist. Originally, i was planning on buying the ipod touch 5th gen because i have a phone with me. But unfortunately, my phone is starting to deteriorate and having problems so i need to replace it so i was wondering how much would be the cheapest ( at least 16 gb) iPhone 4S. I looked at apple singapore and it was about 730 SGD… Is this the same in the stores? Please answer because i need to make up my mind as soon as possible. Please tell me how much (each model with different models) is. I can only afford the phones about 700 SGD or less.

How to get rid of water in iPhone?

Ok so I dropped my phone in water. I was told to submerge it in rice and that will help. It did but I can still see the water on the screen and my phone will keep telling me Charging is not supported with this accessory. Is there a way to completely air it out? Should I leave it in rice longer? Should I give up hope?
