Preview: Samsung BlackJack

Alright I am in a bit of a pickle here ha. I have a treo 650 right now, but I really like the ascetics of the new BlackJack, but I cant quite commit to wanting it 100% without asking a few questions. These might seem like stupid questions to some, but little things like this matter to me when it comes to cell phones. Can the background on the main screen be changed to my liking, pictures and so forth? How easy is it to upload say pictures from my computer, is it like Hoysync with the treo, just plug and boom? As far as MP3's as ringtones, do I have to download anything special, any programs or anything in order to set those tones like the treo? And does it use an SD card for outside storage as well, or is it a different format? Is the phonebook able to store all the info like the treo, and can pictures be set for each contact? So hopefully someone, anyone, can answer these questions, I would greatly appreciate it, and it would further push me towards buying this phone.
