Hello everyone. Please help me to update software for my Galaxy Tab for Sprint. Update from the menu is impossible since I is not in your network.
I know that all the devices from Samsung have a file system rfs. Galaxy S is upgraded to a new and faster systems ext4 or yaffs2.

1) In our phone is possible?
2) What is the quality of custom firmware users?
3) How to update the software on our version?
4) What is the latest official firmware?
5) Should expect a full 3.0?
6) In the custom firmware is a hardware DivX / Xvid?

Thank you, and apologize for my poor English.
