I am using the latest version of snow leopard on my iMac and I would like to download and install Lion using Apple's USB flash drive. I do not have DSL or Cable internet in my area so I am forced to use Sprint's Mobile Broadband aircard which has been working fine with snow leopard. But Sprint doesn't yet support 64 bit for the Lion OS, so if I did download Lion I wouldn't be able to connect to get online and that's no good. Has anyone else had that problem using an aircard and found a way around it? I really want to get Lion so that I don't fall too far behind in the operating system. I hope I described the problem okay. I would really like to get this resolved and Sprint tech support for Macs is practically nil. Thanks for a reply and any information.
