I can't assist with unlocking situations, but I'll be happy to bump this up to the top of the forums to see if anyone can respond to help.
I know this is old news but i wanted to install software update CF03 for my Samsung Omnia (SCH-i910) to unlock the smartphone's GPS for use with other location-based services(Google maps). I just wanted to know if I need to back up my data before installing. I have lots of pics, contacts, and programs(SPB mobile shell 3.5 mostly) i dont wanna lose. Thanks!
