Hi IOri,
Thank you for you post.
For you first question:
>> Backup sms & contacts via gprs/bluetooth
For backup sms, we can use MAPI, which need native code to do it. Compact framework and Mobile SDK doesn't provide the function to access and read sms or email folder. You can try to use the InTheHand Mobile in the hand library, which can access sms . But It is not free.
For how to use MAPI to backup sms, please click the link below:

For backup contacts, SDK porvide Microsoft.WindowsMobile.PocketOutlook , which include OutlookSession.Contacts property to access it, you can enumerate all the contacts and save it.
For your other questions, I suggest you divide it into several threads , where you can get better reply.
Best regards,
