Did you get fully subsidized iPhone 4 price even with AT&T contract 6+ months from completion?

In AT&T’s June 7, 2010 press release, AT&T Mobility’s CEO Ralph de la Vega, stated, “We know that people are eager to get iPhone 4, which is why we moved up the upgrade eligibility date for current iPhone customers by up to six months.”

Six months.

So, then why did we get fully subsidized pricing on our iPhone 4’s when we are Day One iPhone 3GS buyers (not to mention Day One iPhone and iPhone 3G buyers)?

We paid $299 for each of our iPhone 4 32GB models, yet we bought our iPhone 3GS models less than 12 months ago. And, last June 19th, we paid dearly for the privilege.

Was the $299 price we got during our iPhone 4 pre-orders a computer error? Will we be charged another $200 per unit on June 24th? Or did we get it because we paid the full (unsubsidized) price for our iPhone 3GS units last June?

Has anyone else pre-ordered iPhone 4 models at the fully-subsidized prices ($199 for 16GB, $299 for 32GB models) who was also more than 6 months from the end of their 24-month AT&T Mobility contracts?
