activesync and BT question

[poorlyduck]

I remember when I just bought the treo 700wx I could push contacts from a900 easly, now and after doing hard reset and customizing my treo, when I pear it with a900, i dont have any problem but the problem is that a900 find my treo as the owner name and I dont see any options to send cards or anything, I went directly to contacts and tried the option to send contacts one by one, but when it searching for the device, cant find anything. it is weired that when 1st got it, it was very easy and I sent all my contacts.
also I have no idea why my activesync is giving me the option to sync only files, favorites and media, all other options are grayed out.
please if anyone can help me I will really appreciated.
