What is the difference between unlocking an iphone and jailb

[varcalo]

I have had my iPhone for about 2 months. I have a lot of data on it, such as songs and contacts. I synced my iPhone with my computer, but my computer crashed and all of my data has been lost. Is there any way to transfer the data on my iPhone back onto my computer?

I am no expert with the iPhone transferring, but there seem to be lots of articles that offer assistance. Here is one that seems valuable for songs. Not sure if it can do the contacts though. Note that they say to turn off the sync function initially (then follow the instructions) or itunes will blow away the songs on your iPhone.

This next post talks about the contacts working properly with the sync function. That tells me that it will automatically work just be re-syncing your newly rebuilt computer.
