Java applications all use the first configured APN on the Sony Ericsson T610 or Z600. This APN should be a GPRS/Internet APN, not WAP or MMS APN. Each APN on the Sony Ericsson T610 or Z600 has a unique identifier known as a CID, where the CID can be found by selecting Connectivity -> Data comm -> Data accounts -> . iMobixx will always connect through CID=1, so if the current APN associated with CID=1 is not a GPRS/Internet APN, simply create a new APN, copy the APN settings from the APN associated with CID=1 and then copy your GPRS/Internet settings to the APN associated with CID=1. Then, you need an active “WAP profile” that connects using the GPRS/Internet APN associated with CID=1. Visit Connectivity -> WAP options -> WAP profiles and either create a new profile or edit an existing one. In Connect using, select your newly-configured data account. Finally, back in the WAP profiles menu, check that this is the currently selected WAP profile.
