ouch bro - 519 hours...that's gonna hurt. You'd be *so* much better off going somewhere that they have free internet. Think starbucks, barnes & noble, local mac stores, panera bread, schlotzskis, etc...
I'd make the trek to an Internet cafe. I'd be surprised if the firmware wasn't corrupted by the time it completes.
Ive been reading another post about a similar problem, and I was wondering about going to an internet shop that has a fast connection and downloading the update to a DVD , but ive just remembered that none of the Thai internet shops have Mac's only PC's , so this would may be a problem trying to download some thing for an Apple Mac from a PC, Have I got this right ?
Thanks a lot
Off topic but.... whats the current internet scenario in Thailand?
No
