The long-awaited end of the green bubbleNurPhoto via Getty ImagesApple seems all set to launch iOS 18.2 next week, bringing the long-awaited release of feature-rich Apple Intelligence tools held back from iOS 18s launch in the fall. But the next iPhone firmware release also brings the most surprising update in yearsa change to how your iPhone works andfinallyan end to those pesky green bubbles.The saga of green bubbles versus blue bubbles is very much an American thingthe US has been the only significant market which has held WhatsApp at bay, and clearly when your entire social network moves to WhatsAppwhether on iPhone or Android, all users look the same. Its refreshingly democratic and socially leveling.That said, Americans are trying it. Meta and its CEO Mark Zuckerberg celebrated WhatApp hitting the 100 million US users milestone in the summer, and those of you in the US will have noticed the billboards and Modern Family ads pointing out the benefits of seamless, secure cross-platform messaging.None of which actually killed the green bubbles. It seems that this will come down to two government playersChinas Ministry of State Security and Americas FBI. The Chinese started itnot actually MSS themselves, but one of its arms length hacking groups which managed to infiltrate US telco networks. The FBI then understandably warned that US citizens should stop sending unsecured text messages.MORE FOR YOUThats what those green bubbles are of course. They werent actually designed to distinguish social standing amongst teen and gen-z users. What they actually highlight it a lack of end-to-end encryption. To put it simply, blue is secure and green is not. It doesnt matter if its old school SMS green or new kid on the block RCS green. Blue is still secure and green is still not. And so, when the FBI warns Americans to stop sending unsecured text messages, they mean green bubbles.Cue Apple and that surprising update. iOS 18.2now expected next weekwill allow iPhone users to change default apps for the first time. Importantly, this includes your phone dialer and messenger, the very two apps the FBI and CISA have pointed out should be encrypted if at all possible. As youll all know by now, given the headlines over the last 72-hours, standard network calls or messages between Androids and iPhones are never end-to-end encrypted.And so, following the logic, iPhone users should change their default dialer and messenger to WhatsApp or Signal or other fully secured options. Apple offers FaceTime for calls and iMessage for texts, but both only secure iPhone-to-iPhone, so that doesnt work. In one respect, the timing of iOS 18.2 could not be better, but in anotherperhaps for Apple and for Googles RCS push, it could not be worse.Not everyone will do this, of course. But many will. Especially given the FBI warning making headlines across the US in the wake of Salt Typhoons ongoing Chinese hacks, and with no firm end in sight. If some users do change, if enough users do change, then perhaps we can end the green bubble nonsense once and for all. The bubbles would still be green if texting Android to iPhone from iMessagebut if youre using a fully encrypted platform as your default instead, this becomes irrelevant.As we entered 2024, I suggested that it would be the year messaging changed forever, but I did not expect it to run quite like this. We really are in uncharted territory, and will watch with interest to see what happens through December as users respond to the network hacking news and the fallout that will inevitably follow.What we really need is the green bubbles to turn blue, for RCS to be fully secured as another option for users. But despite the GSMA and Google working on this, its not yet in sight, unlike iOS 18.2 which is now just days away.
