I heard a rumour that the software download is so large that without a memory card in the phone the upgrade will not be possible. Is this correct?
n73 firmware upgrade - size of download
Is more or less 60Mb (I don�t remember well)... But I think is independent from card size. Is only with the phone.
isn't it downloaded to your PC and done from there ?
No (maybe for a temp folder). Is a direct and Auto process, always on-line.
You don't need a memory card for the update, it doesn't touch it.
As others have said, its about 60-70mb, gets stored in a temp folder, and then squirted over to your phone.
Wait a minute, N73 has only 42Mb internal memory, how is it going to work then if the file is 60Mb ?
Cheers.
