I'm currently using Xperia X10 (updated to 2.1 OS) and I just bought Xperia Arc today. I was wondering if there's any way to transfer data from X10 to Arc? I think all the contacts will be synced from google account. What about other datas, pictures, videos, ringtones, downloaded applications from the market? Do I need to download all the apprication again on my Arc from the scratch??? Any advice will be very helpful! Thank you in advance.
