Phone Function Does not work - Effect other features??

[WoR]

I just got this off ebay, haven't recieved it in the mail quite yet but i had a question that maby someone here could help me with.

(here is the link http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&it em=25033113148
)

The seller says that the phone function does not work. Would this affect anything else on the phone besides the fact that you can't use the cell service? I don't really need the phone functionality of it wich is why i bought it, i just need a portable organizer.

Does anyone have a clue why it would work fine and then the phone functionality would quit? Has anyone else had this issue with this phone? I'm hopeing its something stupid that could be fixed via software configuration of software update, but then again i've never had a ppc so im not sure what im talking about.

Any help would be greatly appriciated
