On ebay, what does it aim if a cell phone is umlocked?

Answers: That means that it can be used near any GSM Carrier. (Cellular One, Cingular, AT&T, T-Mobile...etc) ANY. even overseas GSM Carriers.

it means that the cell phone dosen't come near a certain service. example: if you investigate sidekick 3 (which is for t-mobile) you could use it with at&t, verizon, sprint, ect.
