When an app needs to use the Internet, iPhone does the following, in order, until connected:
Connects over the most recently used available Wi-Fi network 
 Â.
Shows a list of Wi-Fi networks in range, and connects using the one you choose. Â
Connects over the cellular data network, if available. Â

phone unless iPhone also has a Wi-Fi connection to the Internet. Depending on your network 
connection, you may not be able to receive calls while iPhone transfers data over the cellular 
network—when downloading a webpage, for example.
GSM networks:  On an EDGE or GPRS connection, incoming calls may go directly to voicemail 
during data transfers. For incoming calls that you answer, data transfers are paused.
CDMA:  On EV-DO connections, data transfers are paused when you answer incoming calls. 
On 1xRTT connections, incoming calls may go directly to voicemail during data transfers. For 
incoming calls that you answer, data transfers are paused.
Data transfer resumes when you end the call.

these features and services could impact charges to your data plan.
