If i unlocked my sidekick; would it work with any network...like virgin mobile?

Note : If you have unlocked sidekick 2008, it would be compatible with any other GSM sim cards not with Virgin USA . Because, Sidekick 2008 supports only GSM sim cards . If you want to use Virgin Australia, it will work . If you want to unlock Sidekick, use unlock code . You can get it from any of the online vendors like OnlineGSMUnlock.com to unlock it .
