iPhone UDP ad hoc datas transfert

I'm trying to make an iPhone application to communicate wit开发者_如何学Goh an other wireless device. The other device can send datas via UDP sockets. I just want to know if it is possible to receive the informations on the iPhone, without access point on the network (just an iPhone and the wireless device), and how if it is.

I was looking at UDPecho, by apple, and I think it could be useful.

If anyone had some idea, just let me know what you're thinking about

iPhone 4 with iOS 4.3 can create a Wi-Fi network using the Personal Hotspot feature, which your "other device" could join.

A Verizon iPhone with 4.2.6 may also be able to do this.

Earlier iPhone models can't use the Personal Hotspot feature, regardless of the version of iOS.
