motorwayne: Being new to Android..Q: How can i install the stock ICS mail app onto this HTC device? Apparently I can do it without rooting it, so where can I get it?
Didn't realize you were moving over from iOS - congrats! If you like to tinker with your phone, you'll love Android, and the One X is an incredible Android phone to start on. Let me tell you, it hasn't always been this friendly or smooth.
You can side load apps by finding the *.apk file online, downloading or transferring it to the phone, then installing it using Astro File Manager (great app) or something similar. You may need to go Settings > Applications > Unknown Sources (allow installation of non-market apps). It may be in a slightly different place in Sense 4.0, sorry my One X is powered off at the moment.
That said, I looked around a bit, and it seems like loading non-market email apk's can be hit or miss. You can probably find the email.apk file uploaded somewhere if you google around, but it may not work at this point.
People really like K-9 Mail, you can get it from the market and give it a try. The thing you mentioned with the Gmail IMAP folders is normal, that happens on my Ipad as well.
Enjoy your One X, I'm sure enjoying mine! Even having a good time using Sense again, I'm sure I'll root and flash a new ROM when the time comes, but they've certainly improved things with this release.
Regarding the quick dial -
I'd say the best thing to do is add the "People" widget to one of your home screens - I like the vertical strip. Then you can just tap the person's picture on the home screen and it will automatically start a call (or start a text or email if you prefer).
