I've heard of other people having this problem; is there a fix? There doesn't seem to be a firmware upgrade for the 700p yet; I haven't found one anyway. (I have "1.08-SPNT").
Every couple of weeks my Treo 700p gets into a state where it can't send or receive text messages; none come in, and when I send them, they appear to go out but then never arrive. If I turn the phone off and then on again, everything starts working, and all the messages I should have received in the previous day come in all at once. My outgoing messages are gone for good, however. This happens even if the sender/recipent are on the same network (Sprint). When it's in the bad state, voice calls, web browsing and email still work fine.
