I recently joined wp7 so forgive me but i get a lot of news about these things .. some say yes and some say no .. so i hope someone here with more knowledge can help me out :)

Will the mango update have ...

- Support for tether ? ( usb/bluetooth )
- separated media/volume buttons ? ( coming from android, they are very helpful )
- Support for RTL languages ? ( i live in the middle east ! )
- Support for the operator commands ( i don't know what they are called really, they are the codes which the operators tend to use like #100# , *#1* etc.. )

and sorry if its a separate Question and not related to the topic but .. i can't save more than 1 mobile number for each contact ? if i can then can someone point me to the steps ? ( i use google mail/contacts sync btw )
