I use Outlook and really need a better way to sync Calendar and/or contacts from Outlook to my BlackBerry 8830. I heard a rumor that RIM had some new software but I haven't seen it.
I also need some software to help view .pdf's but that is another thread.
Does that mean wireless? If so, there is software released (or soon to be released in North America) called BlackBerry Unite! Just a matter of waiting for it.
