Do any of y'all that have installed ios 6.1 see an improvement with imessage. I have a concern that has never been resolved. Messages at times deliver within a split second and some take 5-10 minutes. It's getting worse and worse and I need this fixed. I have iphone 5. I'm seeing the problem with multiple people that have the iPhone. They have the same concern sending back to me also. I am hoping the concern is resolved as this makes the phone unusable for texting.
I know the problem you're talking about, but I don't think it will ever fully go away.
It shows a message as
delivered as soon as the iMessage server starts to deliver the message.
So you can send the message, and it may well be that it delivers (or at least starts to deliver) the message to the recipient straight away. These occasions, you will see that it's delivered straight away. The issue with that is if you send a large picture or video, it's saying it's
delivered as soon as it starts to send the attachment to the recipient. If they have a poor connection, and don't finish receiving it, they never will as the iMessage server thinks it's been delivered to them at that point. I don't know if that specific issue has been fixed, I haven't been sending many photos or videos over iMessages to test that yet.
As for it not showing
delivered for 5-10 minutes, I haven't noticed it too much since updating to 6.1. However, this could again be due to the recipient and not necesarily due to iMessages. I saw it a lot messaging my girlfriend when she's home. The mobile data connection at her house is poor, and when she's in her room the wifi signal is weak and low. So sometimes, her phone just genuinely doesn't have a connection so the message cannot possibly be delivered, and I don't see it delivered for quite some time. I don't think that issue will ever go away unless reception/signal improves.
As long as your phone isn't showing the message as still sending, there's not much else you can do whether you're on 6.0 or 6.1. There will still be occasions where the connection from the iMessage server is rubbish for many reasons, and so the recipient still will not receive the message for a while, so it'll take a while for it to show as
delivered on your phone.
Not much help I know, sorry... just wanted to throw in my thoughts on it.
