Hello everyone, first time poster. Only made the move to Mac 2-3 months ago, had an iPhone 4 slightly before that, but loving the experience so far and have no intention of returning to the dark side. Better make my first question a memorable one then... Here goes. Actually, there's two, and both relate to iMessage. iMessage Security One of the features being touted for iMessage is the idea you can start a conversation on one device, and pick it up later on another that's tied to the same account. That's pretty cool, but am I missing something in saying there's a rather obvious security issue raised by that? Facetious Example: Hi, I'm an "unnamed English Premiership Footballer". I've just left the house and used my iPhone to confirm a secret rendezvous with the "unnamed Z-List model" I'm having an affair with. Oh, I've just realised I've left my iPad on the kitchen table at home where my wife is now calling her lawyer. Oops. OK, funny side over, see what I mean? It could equally apply to two iPhones on the same account. Let's say me and the wife have a shared library for instance, we share the same email address, etc i.e. we're one of those sickeningly "together" couples. So much for her "surprise" birthday party I've arranged with all her friends via iMessage. I don't need to mention potential security risks for business users as well. Am I missing something here? Surely there's no way Apple missed this and there's a way to keep messages from syncing to every device that's set up on the account. The only obvious workaround I can see if there isn't is the screen lock code, but that's no use in the second scenario I gave. The problem I have here is that I don't see HOW they could implement this security without hobbling the functionality at the same time. To give you a third example (assuming they DO have something to prevent this happening): I start a convo off on my iPhone, leave it on charge, and move to the lounge, plonk down and start browsing the web on an iPad. I get a message in related to the convo I started earlier. How would it "be decided" which devices it appears on? It'd just appear on both by default, no? The ONLY way I could see around this is that iMessage has a setting (either at an application or (ideally) individual conversation (or rather, by contact) option to share (or not) conversations with other iOS devices on that account. But it's one hell of a strung out way of doing things. If iMessage is ever rolled out to Mac OSX devices as well to create true message portability, the implications are even more comp,ex. Anyone know? Is it basically "Screen Lock your device if you're worried about that kind of thing (even though Screen Lock has limitations dependent on circumstances (see above)) 'cause there's no other way of doing it." iOS "sensing" I must admit I think it's cool that your device will "know" (I would imagine via checking-in with Apple) whether the device it's sending a message to is an iOS 5 device or not and will consequently send the message as either an iMessage or a text/MMS accordingly. Great. I also know you can turn it off if you want to send SMS exclusively (although I can think of few reasons you'd want to). However, my question is related to that. Let's say you can't get a data network connection. This occasionally (nah, make that ALWAYS) happens for me when I go to watch my football team play. Traffic congestion means the data network slows to a crawl (too many smartphones concentrated in the same area, everyone checking out the scores elsewhere) and you're lucky if you can get a data hookup. However, cellular works fine. I can still send & receive SMS, phone calls are fine, etc. It's only when I leave the vicinity I suddenly get 15 emails, Facebook notifications, etc. In that kind of situation, how will iMessage react if I send something? Ideally, I'd like it to say "I can't get an answer from the Apple servers as to what kind of device I'm sending to, connection timed out, screw this, I'm sending a text". I suspect it won't be that way though, 'cause I've also considered the reverse scenario... what if someone sends me an iMessage? From their end, everything seems fine, the only clue they'll have I've not got the message is the lack of a delivery receipt (if they even have those turned on). It'd be cool again if because the iMessage couldn't be sent, it would revert to a text, but I can't see any way that's going to happen because a person could then be charged for a message when they had no intention of sending anything other than a (free) iMessage. See where I'm coming from?
