I Want to buy i-pod or i-phone or mp4? Please tell me which works best and which sounds best?

I-pod offers the itouch, wich has the capatibility of an iphone without the phone. It offers free internet where wi fi is. Also there other ipods are pretty good. Although zunes play music and movies too, and are cheaper. mp4 would problly be cheapest. iphones are really expensive, and you have to pay for extra stuff. If you use your phone a lot I wouldn't recommend a touch pad, they're not very reliable.

I dunno the answer for your other question, sorry.

I hope this helps though

I don't know much about all the ipods and mp4's but I think the iphone would work a tiny bit better than the other two. But that depends on lots of things like do you use your phone a lot if yes get the iphone if no... ipod nano works second best.

I think you should get the iphone (my opinion)
