Phone functions? Help!

[passosjd]

Hi, Ive just bought an UTStarcom PPC 6700 Apache and am really disapointed with the phone's functionality.Some really basic functions, found on early mobile phones are missing and I cant figure out why Microsoft ignored them.

My two main problems right now:
1) Sound volume - there are no preset profiles for sounds and vibration (like in ALL normal mobile). Can I create sound profiles? How?
2) Contacts - Can't set a ringtone to a group of contacts, have to set the ringtone to each and every of my contacts (there MUST be another way)
3) No OBEX - Any hack posible?

Is there anything I can do to improve my phone? Can I change the entire OS?

Thanks,
D'Acosta
