I checked the iBurst website this morning, and amazingly, they had posted 64bit drivers for most of their devices. However, they have not yet released drivers for the old and new versions of the PCMCIA modems. I contacted the helpdesk and they stated that they are still working on the drivers for those modems.Also, you can use the Vista driver in Windows 7. I tested it. Works perfectly. Right-click on it and run it in Vista compatibility mode.
