What is the difference between the signed and unsigned versions?
Each mobile device implements a set of security policies that determine if an application is allowed to run. As a security measure, some devices require downloaded applications to be signed with an appropriate certificate to be allowed to run. BOLT is signed with third-party certificates from VeriSign and Thawte. These “signatures” enable the device OS to confirm BOLT’s authenticity, provide access to secure device APIs, and help ensure that BOLT is free from malware and/or viruses. Signed applications enable you to use BOLT with fewer permission dialogs for file and network access from your device’s OS. However, a few platforms including Motorola P2K do not allow installation of signed builds. To enable installation on these devices, an unsigned version of BOLT, with no certificate, is also offered.
