It's a fact that a beta firmware should never be considered in a production environment, but once you know that and assume the risks derived of its installation, it's time to judge.
I've tried it on both my iPhone 4S and my iPad 2 3G and for me is running really well, with some minor flaws.
Maps needs to be improved a lot and at least by the moment I don't like what I see. I'm located in Spain, so it can be a location related problem, altough it says that map data are obtained from TomTom. You can install Google Maps as a shortcut in the desktop and it works quite nice.
Screen brightness is a bit out of control. When I first installed the firmware, both the iPhone and the iPad began with a really dimmed screen, around 20% of brightness. I corrected it and brightness at 50% thrown the same brightness as 100% before. I deactivated the automatic brightness and activated again and now it seems to be working OK, but as soon as I restart the device it goes crazy again. By the way - maybe is placebo effect - but I perceive screen colour more accurate than before, as if it were using a better calibration profile, without a slight yellow cast as before.
Facetime settings can't be accessed. When you try to enter them the settings app freezes.
Photo Editing in the photo roll has corrupted some photos. Be careful with this and always work on a copy if it's a unique photo you can't replace.
Music app is redesigned and it need to be polished, but it works well. Some weird behaviour sometimes with iTunes Match when switching between tabs, but now I've synced around 400 albums it works way better than before, loading every album cover much faster. Sometimes it syas you can't download the album, but it works anyway.
Air Video doesn't play the remote server files. I've published a post in the Inmethod forums and hope they get it corrected soon because I'll miss it.
I have
more than 200 apps installed and almost every app I try works well. The most common Twitter, Facebook, WhatsApp, Viber, Spotify, TuneIn Radio, Weather Pro, SoundHound, iBooks, GoodReader, TomTom, Motion-X GPS, CityMaps2Go, and a huge etc. is running fine so far.
I'm not a huge fan of
iCloud and I'm syncing my contacts, mails and calendars with my corporate Exchange mailbox. But the iCloud services I'm using works well.
And the following three are updates that in my case make worth the update by themselves.
Bluetooth music streaming using AVRCP works better than before. It seems that the bluetooth link is more stable and less prone to interferences.
Siri is finally available in Spanish and if it gets improved, it's going to be really useful. I want to know why it isn't available for the iPad 2 3G, anyone knows?
Voice recognition integrated in the keyboard has finally convinced me to speak to my phone. It's nothing new and Dragon has it with Dictation, but being able to use it anywhere you need to type makes a difference.
