I have been researching smart phones till I am about to lose my mind...

3 questions that need clarification:

(1) can I receive yahoo messages...small company and we use yahoo

(2) will I be able to open/manipulate and return email attachments
(word and excel docs). I will need to make changes to the documents immediatly and return them quickly for my clients.

(3) can I create documents on this thing and email them to my partners?

THANK YOU SO MUCH FOR HELPING ME...I AM SO CONFUSSED

1>If you are referring to Yahoo Messenger, then yes you can use it. There are quite a few IM programs that are available for the phone and you will find a more comprehensive list of those Apps by doing a simple search of the forum. If you are talking about Yahoo emails, you can receive POP3 email on the blackberry but there is a small amount of delay on the device.
2>You can open attachments and save them as far as i know. You can download the equivalent of Microsoft Office for your blackberry....i believe its called eoffice but i may be wrong.
3>Yes you can create documents on this "thing" by using the eoffice programs.

hope i was of some assistance. I can assure that this phone will do everything that any other smart phone will do and may do some of them better than most smartphones so i strongly suggest using it. Personal preference of course but im sure there isn't much you need it to do that it wont/cant do for you.
