Using e-mail for video upload doesn't make any sense to me: a 1-minute-clip recorded with N900 is over 20 MB in size. I don't know what the size limit is for attachments in the Maemo e-mail client, but it wouldn't accept a clip of 50 secs - let alone the limits of e-mail providers (I think 10 MB is the max I ever heard of)...
Anyone happen to know the reason why Cutetube doesn't allow video upload?
