    As i understand it, verichat uses sms to send and receive its "instant messages." For instance, GPRS users would probably get charged for every IM you send and receive via verichat (or have them deducted from their sms bucket, depending on their plan).

    For Sprint users, billing for verichat IMs has not been an issue, since unlimited text messaging (notifications) and shortmail has always been included in unlimited Vision. So when MO-SMS launches and replaces the shortmail system with a more typical pay-per-sms billing model, would Sprint Verichat users start having to pay for instant messaging on Verichat?

    Does anyone know if Verichat will continue to work as it does now once real SMS comes to sprint?

    Why doesn't someone just write a unified IM client for the Treo that uses TCP/IP like on a computer? What are the advantages of Verichat going through sms?

    There may be extra charges, but it will work. Now for some clarifications- Verichat does not use SMSs while it is running. It only uses them when you exit the app, presumably since OS5 is not multitasking, and VC cannot keep the internet connection active while another app is running.

    It's funny that you say that, because Chatter (which will be released next week) works entirely with TCP/IP, never using SMS at all. There are advantages to both systems; how someone weighs these pros and cons will be a personal matter.

    Pros of TCP/IP...

    1) SMS will probably be a charged for by the various wireless companies, so this WILL become an issue for SMS-based messaging products. It's true that Verichat only uses SMS when you're not "in" it, but in general, you don't want to be tied to being "in" any single app, no matter what it is. So realistically, you're going to be OUT of Verichat (or Chatter, my program) more than you're in it. Since Chatter works entirely with TCP/IP, there will never be additional costs for unlimited data customers.

    2) SMS is, in my experience, problematic. Messages typically arrive very, very quickly, but sometimes they can be delayed by minutes or hours. Given the addition of extra servers in the loop, this shouldn't be surprising.

    3) With Chatter, messages can be sent instantly without waiting for a connection to be made. This is only true of Verichat when you're "in" the program.

    4) With TCP/IP, incoming messages can be of any length, rather than limited to 160 characters. With Chatter, you can get messages of any size (and send them) at all times, without the size restriction.

    Cons of TCP/IP

    1) You can't receive messages while on a phone call. It's also possible that there are times when an SMS message might get through whilel data service was difficult to obtain, due to a weak signal.

    2) You are using more of the data channel, so the odds of missing a phone call are somewhat increased (just as it would if you used any web-based app).

    You pays your money, you takes your chances...
