Best Buy's website suggests that a new iPhone will be introduced today

UPDATE: The Apple Event brought us a bunch of exciting product announcements. No new iPhone in sight, though. Here's what's new:
Even though Apple isn't expected to unveil any new iPhone models today during its "Time Flies" event, Best Buy thinks otherwise. On the big box retailer's website today (via AppleInsider) a screen protector for the iPhone SE Plus surfaced. The accessory is produced by BestBuy's own in-house Insignia brand and is listed at $14.99. According to TF International analyst Ming-Chi Kuo, such a device isn't expected to see the light of day until early next year.

Best Buy lists a screen protector for the Apple iPhone SE Plus
We would imagine that the iPhone SE Plus will look like the iPhone 8 Plus with its 5.5-inch LCD display carrying a 1080 x 1920 (FHD) resolution. Similar to what we might see with the fourth-generation iPad Air expected to be unveiled today, the iPhone SE Plus could be equipped with a fingerprint sensor integrated with a side mounted power button. However, the placeholder that was used with the listing appears to show cutouts for a notch and a Touch ID/Home button. Having to use a placeholder is one clue revealing that you shouldn't expect to see the phone introduced today.
