Hi,

two questions:
1. Do you use Mac or PC??
2. What version is your Iphone on now? 2.2?

Dont worry as of today ANY iphone on ANY version can be unlocked.

Im pretty sure that Ziphone is not uptodate anymore.
I recommend Pwnagetool or Quickpwn to unlock/jailbreak current versions of Iphone software.
