I'm not very good with mobile broadband terms, just wondering if this phone will work with the optus network in Australia? and would the blackberry bold 9930 work with optus as well?
If the Blackberry 9730 and 9790 are free from network restriction or they are locked to Optus network, then they would work fine with Optus network Australia. If they are network restricted to any other metwork, Then they must be unlocked to use with Optus network. A Blackberry mobile phone can be unlocked safer and easier using unlock code. An unlock code for a Blackberry 9730 or a 9790 can be obtained from http://www.simpleunlocking.com/blackberry-unlocking-service/rs16wp10/ at affordable cost with free unlocking instructions. All the best mate.
