While I would never ditch the Sense-based OS for vanilla Android, I'm excited about the prospect of being able to switch back and forth, to be able to do benchmarks between the two OS versions with the exact same dataset installed, and to generally choose which version suits my current needs. (Y)
This isn't an urgent issue, just something I wish I could change.
When the Nexus 7 talks to me, such as when I use Voice Search to ask "what time is it," for example, it responds with an English accent. No matter what I try, I can't seem to make it have an American (or Canadian, more specifically) accent. All my locales, are set to U.S, but it still speaks with a British accent. I even checked the build.prop, and it seems my locale is set to U.S. there as well.
MCR's are designed to need no wipe between installs, but as I'm sure Paul would say if he got to this first: Try installing updates with no wipe, but if there are problems, wipe and try a fresh install. AND DON'T FORGET A NANDROID BACKUP BEFORE YOU DO ANYTHING.
The current release is more of a beta-quality release as I understand it, so don't be surprised if it turns out that you need to wipe.
Oh, by the way, I find that the Hi MSN Beta is pretty good. It's not the prettiest app in the world, but it connects directly to MSN without having to sign up for an eBuddy/Palringo account as well, which I find terribly annoying.
Actually, the Google Talk .apk is different from the IM.apk. The IM app actually includes support for Yahoo and MSN messenger. For some reason it doesn't show up in the Android (ION) that I'm currently running, however it does show up in some builds. I believe the Vogue-Hero build by Zenulator on XDA is a build that it does appear on. However, when I go to sign into MSN with it, it errors out because it can't access my mobile number from my SIM card. (The vogue is CMDA, thus, no SIM.) I'm real busy right now, but when I get some spare time, I plan on trying to fix that for cdma phones.
Some people at XDA have been working on getting it going on the Dream here:
