I just came across these steps in Wired to unlock your iPhone:

1. Update iTunes and Iphone app installe

2. Download Pwnage Tool

3. Select “simple mode” and install Cydia

*If anything goes wrong you can reverse the process using the iTunes System restore.

**I don’t own an iPhone.  I use a Blackberry because I would rather accidentally leave a Blackberry lying around then an iPhone.  There’s no comparison in terms of privacy, encryption, and the confidentiality of your data.  Maybe this will warrant a future post…
