If this B5/GM version is so called the version that Apple use it for final testing before the official release, then im really disappointed with Apple these days, how could they still leave these 2 very noticeable bug in GM version which we most probably's gonna see it too in the official 6.1 1. AssistiveTouch, well this thing will just shrink when u use it to quit some app and press it again, u actually have to press it twice to get back to the menu again. Try use AT quit settings app, and then press the dot again, you'll get what I mean. 2. Notification delay, well, whatsapp for instance, even in B5/GM version, when i off my screen after quite some while, ppl send me a whatsapp text, i wont be able to receive the notifications, I have to actually go in to the whatsapp to see the new texts. Isn't this bad? Apple do you means I have to keep my phone awake just to check is there any new incoming msgs? and funny thing bout this is after i read the whatsapp text..i put back the phone to sleep again, till then i received the notification, it then leave a 'red 1' on top left of whatsapp, I thought i got new text again, who knows its the text that I have read..LOL I was thinking, U sent me a notification after I read my msg, hey, and there's more, back in 5.1.1 if i receive offline msgs overnight, the next morning when I connected to wifi, I immediately will receive the notification if there's offline msgs, now this for all the ios6 version, same story, the phone wont notify me and I actually have to go in to the app itself to check new msgs. Idk man but if official 6.1 still having this main 2 problem I think im gonna quit.
