I have an old iPhone 3 that was using AT&T as the phone carrier. But since June 2010, I started using the iPhone 4 and that iPhone 3 has no phone carrier any more.

It connects to my home network using WiFi. But when I try to send my old Notes written on the iPhone 3 by email or view weather or stock data, it can't access the network.

Is it true that an iPhone 3 that has no phone carrier won't be able to use the WiFi to send or receive data? Thanks.

After you switch to a new iPhone, the old iPhone will still be able to access data over WiFi, just not the 3G network.
