I have a friend that has had this PDA for a while (about seven years), but never used it (or rarely). Now, since a lot of us have PDA's, the person wants to start using it. It has the ActiveSync 3.* disk, and I do not know if the battery is still good. I am charging it right now. The PDA has been used for about one hour it's entire life.
What will I have to do to get it as up-to-date as it can get?
I have friends that have PC's, but they all use ActiveSync 4.2 or 4.5. Will it sync with 4.2 or 4.5? If not now, can it in the future, with a little help (from friends like y'all)?
If not, can the PDA be update without syncing it. Can the programs that it needs be put on by CAB files? It has a CF card slot.
If it needs a new battery, where can I find one for this PDA?
The person does not need it to do amazing things, but wants to use Word and read books on it (it comes with Microsoft Reader - do not know what version). That is all. Okay, maybe have some use of contacts and use the calendar, but nothing more than this.
Please help me, help this person.

Thank you ahead of time.
