i've researched this but yet to determine if this has been fixed. a handful of other ppl have experienced the same issue with vm and ultrasnow. i loaded ultrasnow v1.2, rebooted. went into Settings and saw the new Carrier setting. good so far. now visual vm is not working, meaning, no new vm can be accessed via the device. vm can be left by callers but i cannot retrieve the messages from the device. also when i try to listen to my custom greeting i receive an error message "voice mail cannot be accessed at this time". appears anything that requires accessing the vm servers from the device does not work. retrieving vm remotely via landline still works. a thread mentioned the unlock wipes out the device's apn settings, not sure how valid this is. i uninstalled ultrasnow and all the vm that was missing dropped into the vm box and all works fine. i repeated installing and uninstalling ultrasnow, rebooting several times, and i get the same results - ultrasnow breaks visual voice mail. anyone else having this problem find a solution yet? device specs: iphone 4, jbroken via limerain, running v4.1, baseband 1.59. thanks.
