Had 3.0 GM on my iPhone 3G since Friday, MMS via Optus seems to work, the OS is still buggy, slowdown, unresponsive buttons, wierd freezes (Safari, had to force restart) and weird crashes (3rd party apps - Darkroom for example), transition into search screen isn't all that smooth.
I also tested Find my iPhone, it sort of works in Sydney, the message I tested took almost an hour to get to the phone, when I tried to find it on the map, it showed up the last place I lived - from 3 months ago! How could that be? It did eventually work but Mobile Me seems not very acurate in that it says the phone is "Offline" when it's next to me and not turned off, strange! Also while it said "offline" (the light under the phone becomes greyed out, same as MacRumors' forum lights) then you can't make it look for the phone, I wonder WHEN does it become "offline"? And say if the thief switches the phone off, will it be offline or what? need more clarification.
I hope later this week when they release the final version will have all these issues resolved. Also be aware to activate Find My iPhone you HAVE to activate Mobile Me's email account and turn Push Notification on you iPhone, for me that has a large data plan it's okay, but if you only have a puny 500MB plan then I'd becareful if you don't wish to go over and having another email account on my phone (I have 3 already) can be a bit of pain, back and forth, know what I mean?
Anyone else had similar experience?
