I'm looking at the Wiki for Enabling Internet on Samsung Smooth SCH-U350 (the easier way). I have a few questions and concerns that don't seem to be addressed in the Wiki.

What is the possibility that following those instructions will mess up my phone? The Wiki looks like it's 4-5 years old, so I don't know if it will still work. If I follow them and it does mess up my phone, will I lose my money/minutes?

Thanks for the help. Sorry for the ignorance. I just can't deal with having a messed up phone right now, there's too much other BS going on.
