急需一段买手机的英语口语对话，不知有哪位朋友愿前来帮忙？如果能够帮得解决此问题，某感激不尽…

A: Hello sir, may I help you?

B: Yeah, I accidentally dropped my phone in the toilet.

A: I see. Well, you have come to the right place. We have over one hundred models of more than twenty leading mobile phone manufacturers.

B: Sounds good. I don’t want it to be too expensive, maybe something mid-range.

A: We have this new HTC smart phone.It comes with the Android OS so you can download applications. It also has a built-in camera, mp3 player and touch screen. It works on the 3G network so you have fast access to the internet wherever you are.
 
B: What about Wi-fi?

A: Of course! You can access the internet from any hotspot（网络接口） as well as from home.

B: One last thing. Is it waterproof?
