I got BerryTunes On my Blackberry but i do not know how to sync my iTunes.
If you know how could you help me. I have so many songs I want on it. Thanks!!

I don't think BerryTunes has anything to do with iTunes. It is an MP3 player only, just like the one built in to your Pearl.

and i believe itunes is a certain kind of format that only lets the files play on your ipod and nothing else

itunes format will play on the Pearl. Somewhat of a hassle with tunes purchased from itunes, but other than that, songs in itunes will play on most music players and DEFINITELY on the Pearl.

MarkSpace Missing Sync for BlackBerry has the ability to sync your Pearl with iTunes.

Moved to Aftermarket software.

i sync my curve with itunes everyday no problem using itunes agent, google it. its really easy to use will put any itunes music bought from itunes or not bought right on your bb, it will also work on mp3 player that shows up as a drive in
my computer, if you need help let me know

I have a mac not a PC.

I may be totally off base and it may not relate, but I always hear about "missing sync". I thought it was for Macs
