Allow the Zune player to recognize and play FLAC and other lossless formats natively.

We need the ability for the phone to automatically push changes back to the server. Right now, the only way to do this is to manually click the sync button. After deleting or moving emails, one has to click the sync button (or wait for new email to arrive) for the changes to sync back to the server. This really needs to perform automatically immediately after the action has been performed.

Revert the change in Mango where the hardware search button always brings up Bing and is no longer contextual, or allow us to toggle this.

Windows Phone needs VPN connectivity. Need I say more? Android has it. iOS has it. ****, even BB has it. If WP is to succeed in this increasingly "on the go" and mobile market, its users have to have VPN connectivity.

Now wp7 only got 3 levels of brightness adjustment. We want a smooth linear adjustment like iOS and Android to customize our own brightness level.

To be able to play these apps like iPhone users

If the phone is switched off, the alarm will still sound. Why its not already possible I have no idea.

Support week numbers in all calendar views. Week numbers are heavily used in several European countries as well as other places.

For maximum global coverage should support all three kinds of week numbers (as Outlook does)

Integrate Google+ into Peoples Hub, same as you do Twitter/Facebook/LinkedIn/etc

Native video calling should be provided to allow users to make video calls over 3g network without being dependant on 3rd party apps.

Would LOVE to be able to copy files to and from the phone without using zune software, just like with regular USB stick (like WM6.5)

Please support tamil and additional south indian languages (Telgu/Malayalam/Hindi etc) support on WP7

Search in the calendar is a must have. When I need to edit a calendar entry, I have to try to remember the current date

Widely anticipated in Mango, but eventually unimplemented, the USB/wi-fi tethering function available to all second gen phones must be made available to early-adopters.

There is nothing special to be done technically, Windows Phone has already support UNICODE character set, please add missing font to OS

Get the carriers and manufacturers out of the update process. Carriers should not be allowed to arbitrarily block updates.

Pressing the hardware search button should bring up a universal search box which searches through everything on the phone.. apps, contacts, calendar, web, images, etc.
