Having just come back from Oz I bought my Telstra Sony Ericson Xperia X1a back with me because I saw that it was compatible with the XT network (checked the IMEI on telecom's site). However, and I do understand that it is not fully supported because it wasn't purhased here, I would like to check that all the settings are OK.  I can make calls and send text's no poblem but cannot clear my voicemail, and also want to sync to Exchange at work (I can do it using Wi-Fi) and Push Mail.  Does anyone have a full list of all the settings I would need to check to ensre smooth operations.  I.E. Connections, HSDPA/HSUPA, CSD Line Type, SMS, GPRS (if needed), VoiceMai number, etc.
