John Gruber from Daring Fireball revealed today that the CDMA iPhone 4 with codenamed N92 is entering the engineering verification (EVT) stage, one step before the design verification test (DVT) stage, which is right before manufacturing — and right on time for a possible January 2011 launch.
He states that while he doesn’t know about the negotiations between Apple and New Jersey-based Verizon Wireless, he does know that it’s not in production just yet, and hasn’t reached DVT status (device verification test — like Gray Powell’s infamous stolen unit).
Additional signs of CDMA phone release is when on Monday, AT&T filed report with the U.S.Securities and Exchange Commission warned that some of its smartphone exclusivity agreements will soon expire.
Rumors of Apple creating iPhones for US carriers other than AT&T exist for a long time. The latest is a T-Mobile rumor that came last month with a report saying that Apple and T-Mobile talks are in an advanced stage.
Until Apple makes an official announcement, we won’t know for sure. We have to take all of these reports with a grain of salt. However, there is plenty of evidence suggesting that the CDMA variant of the iPhone 4 is going to Verizon Wireless first.
