SecureGSM for, um, secure GSM cellphone calls
Anyone touting "unbreakable" encryption is just asking to be shown up, but an Australian company by the name of SecureGSM is offering a new app for Windows Mobile-powered Smartphones and Pocket PC Phones that uses 256 bit encryption to protect your calls from electronic eavesdroppers. All that privacy better be worth it: they're charging AU$249 per user license.
