Can I sync this phone with a mac computer?

how to view full screen video?

No, it's unable to transfer sms to memory card, just to the sim, there's no option for it. Hmm According to what I've saw in some pages, some phones may reproduce videos on fullscreen, mine's doesn't do that (it's the metallic gray). As for the music, my cell comes with a 512mb microSD memory and adapter to connect to the PC, fortunately it worked for me because I have a 5 in 1 Card reader in the pc. I'm looking for themes for this cell but I've not lucky yet. But I've tried to install java games, and it worked, you need a program called JAD MAKER, because these new generation of cellphones needs an additional file to run .jar games, this file is a .jad file that have to be in the same folder of the .jar game.
I download it here: http://rapidshare.com/files/149556247/JADMaker.zip

steps: arrange the .jar file of the game you want to the window application and then, it will create the .jad file. put both on the same in the same folder on the microSD if it came with your cell.
What I don't like it's the music player, it's kinda simple but the earphones are very great, neat and rich sound. I'm going to download the java kd player to see if it will work on this samsung:

Ok, that's all. Ah, by the way, some models changed the play/pause button function, some of them open the WAP function and others (the news) the music player. mine's open the f$!$cking WAP that I accidentaly push it and always eats my charged salary. funny isn't it?

can sms be stored in memory card and how can we upload new themes?

can we download in this mobile by any cable or code......?
This is super mobile.....
