Unlocked/Unlockable iPhone 3G?

Question

I've been looking on eBay for a cheaper iPhone 3G and noticed that many of them said that they were "Unlocked" or "Unlockable" Does this mean that I would be able to use it on a different plan such as sprint? If this is not what it means can someone please inform me on what it actually means. Please and Thank you.

Answer 1

Unlocked phones can be used with different networks. But iPhone won't work on Sprint. Sprint is CDMA network and iPhone is a GSM phone, they're simply incompatible. The iPhone will only work on GSM networks like AT&T and T-Mobile in US. If you need unlocked iPhone, you can mail me or talk with me on Yahoo!
