Just got this information and posted in my blog.
Basically you buy an Okta Agent Windows Mobile smartphone, sign up for 24 months with a Telecom to FLEXI Business or Team Builder mobile voice plans and get the new Okta Agent Free Email plan - one year of free mobile data for e-mail usage.
Fair use applies, but you'd be pretty safe using mobile email and downloading some attachments and some light browsing.
Not to be used as a modem...
Great move, Telecom!
