Best way to transfer data on BlackBerry

I am making a voice note recording appli开发者_StackOverflow中文版cation and it should send voice notes from the BlackBerry to a server. What the best approach for doing the data transfer?

For large data transfers it is best to use HTTP (i.e. HTTP POST the data to a server) using the following transports:

• Wi-Fi (if available)
• Direct TCP (need to specify APN on many GSM devices)
• WAP2 (not all carriers support this)

You could try to send data over BIS/BES but there are usually limits to the size of transfers over those transports - plus you need to be an Alliance Member with RIM in order to use BIS.
