What are them iphone things called?

I want one of them phones which is just like a normal telephone which you attach your iphone. You place it on the slot to like a normal telephone so it makes you can use your phone like a house phone might sound really stupid but I have searched amazon and can't find anything?

I refuse to have one - I only want one with a cord on it… But I think them things is called iTelephones. You gets em at the Walmart.

"so it makes you can use"?

… Anyway!
Have looked at numerous docking stations / adapters for cell phones and I-phones specifically and found Dock - N-Talk by Phone labs

and Merge by Cidco (only good with Motorola phones)
