I have a N900 & trying to do the 1.2 update. When I do this on the device, it prompts me to do the update using the PC desktop, & that I cannot do it through the N900?

My girlfriend also has a N900 and she had the update pushed to her phone?

The problem is, we both have macs & I have no access to a windows box to use the PC Desktop to try & run the update?

Any help here? Thanks :-)
