as the header Content Length says 900. But the header of the .gif says the size 1192. Why is the Content Length Header value is wrong from the Nokia phone?
Exactly which Nokia terminal are you using? Is the image you are sending available somewhere we could download it to try ourselves? (Or just tell us the exact size (w x h)-- just so we can simulate as close as possible exactly what you're doing)
yes, the length certainly looks wrong - we'd just naturally want to "see it for ourselves" -- do you have the actual binary of the message sent?
