Incoming Calls / Texts not coming thru at all (HELP!)

[primer]

Hi all. Im a newcomer here and to palms in general, and really love the look of my palm pro i purchased last week. Sadly, i have quite an issue with it. I bought it used from a third party (sigh) and i am having hell with it since activation.

Everything works fine on the phone, except that I do not get notice of incoming calls or texts. I can make calls, send texts, use wifi and evdo, but nothing incoming will show up on the phone. only randomly will several texts show up all at once, only to start not going thru again.

ive done extensive tech support thru phone and online, as well as dropped it off at a service center for the weekend. Ive hard resetted who knows how many times and am running no custom cabs. I have the programming pw number to get into the phone thru ##778#, but all the values appear correct. Pretty much every person ive talked to has given up and told me it will have to be sent to factory (for a $130 charge since its used). is the phone DOA? please help!
