Facebook contact list uploader

Hi, I have uploaded manualy contact list with 4000 contacts(I have tried with 7k, 8k but it does't upload file) and I got message like "you have 500 friens who are on fb" and "1900 who are not" but what with 1600 other?

is there fb limit on contact files with max. 500 contacts to be sent invitation and how can I reach other 1600 I send invitation?

and what are the limits? On my new account I have upload 10 files with 500 contacts and get stoped for 48hours, after that 5 files with 500 contacts each and stoped by fb again.?

Sorry to hear that. I didnt meet this matter before. I am waiting for some owsome pp to answer.

switch to email contacts (gmail, yahoomail etc) upload your contacts to your emails and your good to go..

I've run into the exact same thing. You shouldn't worry.

If you "select all friends" and click the "send invite" button, the next screen will show a message (right above the section to invite new friends to facebook) that will say "You have sent 1600 friend requests"

It seems as thought the window for individually selecting people is limited to 500 (i guess for bandwidth reasons) but your friend requests are actually going through.

But take it easy on the contact lists, don't get banned.

Thank's for help.
I tried to switch to email accounts, but Gmail has disabled support to fb, and with Yahoo there are limits.
IlanN is actualy was right. Anyway whole my idea was to check who from my email list is on fb and to get they names and ids. And the problem was that my email list is huge, so for the moment I use new graphAPI to check and foe last 48 hours seams that everything is working. I'm checking 20000 emails per day. I don't know if there is some faster solution?
