The original iPhone SE was announced in March 2016, but it didn't get a significant update in 2017. (It just got a bump in storage to 32- and 128GB.) Instead, it's looking like the iPhone SE will get an update in spring 2018, with March looking most likely. Find out more about the next Apple event here.
However, a report from a Chinese website at the end of February 2018 is suggesting that the iPhone SE2 will launch at WWDC in June. The last time Apple introduced an iPhone at WWDC was in June 2010 and we think it would be an unusual fit for Apple to introduce a new version of its entry-level handset at that show. WWDC is a developer conference with a particular focus on software and high-end products.
A FocusTaiwan report in August 2017 suggested that the new iPhone SE would launch in the first quarter of 2018. And in Feb 2018 the Taiwan Electronic Times (via the Chinese-language site MyDrivers) predicted an iPhone SE 2 launch in March, albeit with minimal design changes from the SE.
Another report, this time by the Taiwanese market research company TrendForce, believes a new iPhone SE 2 is coming in the first half of 2018.
Another report claims that the SE2 will launch in India prior to launching in other territories. This sounds dubious to us, although it might fit with Apple's plans to offer a cheaper handset to certain territories (normally Apple does this by offering an older version of the iPhone to certain countries).
The iPhone SE is currently available in 32GB and 128GB versions. In the UK the 32GB model costs £379; 128GB is £479. (For comparison, in the US the iPhone SE costs $399 for 32GB and $449 for 129GB.)
