Help with Iphone 3g!?

Question

Oki I want to know 2 things, what is the difference between unlocking the iphone 3g and jailbreaking it?

Also, I live in Scandinavia, Can I use an american software to jailbreak it or unlock it ?

Answer 1

Unlocking allows your iPhone to make phone calls with any compatible carrier.  Depending on the compatiblity you may or may not be able to use additional iPhone features:  SMS, Weather, GPS, Internet, Youtube, Stocks, Push eMail, ect....

Jailbreaking your iPhone allows you to download unauthorized software to your device.  Typically this is very unsafe, as Apple verifies the software will not destroy your phone.  Jailbreaking your device may allow malicious users to tempt you into downloading "free" games and where they can download your contact information, internet surfing history, account information, track button presses, ect.

Good luck.
