GPRS v. 1xRTT voice/data psylent, << Looks like the GSM version may be the way to go, as far as being notified of incoming calls during data transmission. Do you know if caller ID is available when so notified? PCS definitely sends callers to voicemail if the device is actively transmitting data (up or download) at the moment the call is received. >> A few qualifications on this GSM capability. A few factors are in play. On the client side the device needs to be GPRS Class B which most are now I believe. Class B allows making and receiving calls while simultaneously being registered with GPRS services and there is software on the phone that governs whether or not caller ID from phonebook registry displays and how a suspended download is resumed or restarted. On the network side Network Operation Mode (NOM) governs. A NOM I or II GPRS network configuration allows a Class A or Class B handset to function as designed but if configured as NOM III the Class B handset functions as Class C which dictates non-simultaneous csd voice and data or packet switched data. This will cause auto redirection to voice-mail (or a busy) if handset is using GPRS. My golf mate who roams here and oversees runs into that situation frequently. << SMS on PCS would be most welcome. >> Yes. for all concerned, whether on PCS or using another provider. I'm assuming they will take advantage of intercarrier messaging along the lines of what AWS, Cingular, and Verizon are doing, removing the last major obstacle for SMS in the US. I listened to Denny Strigl of Verizon on a CC about a month back and he was really singing the praises of SMS as an ARPU builder. Although PCS is only starting with 3 models capable of SMS-MO initially, I suspect they'll require it on future qualifications. Next step is interoperable MMS. Have you, btw, spotted the Treo600 GPRS version available in the US yet? Best, - Eric -
