This application is necessary, but has a small problem that is causing me problems.

When I'm in a book and conincide converación time a request for data connection, if there is no wifi interreumpe the conversation to switch to 3G.

Is it possible to modify the application to avoid this? There are two solutions:

1) Reject the GPRS data connection to end the conversation.

2) Connect via GPRS while maintaining the type of connection you are at that time. If you are on 2G, then continue on 2G.
