Just wanted to share my experience getting my T|X to tether with my Blackberry Pearl (8110). My data service is the "CINGULAR WAP GPRS" variety, haven't tested to see if I can get other AT&T services to work. Also note that I have not gotten Dialer to work, and any sends from the Palm to Blackberry have to be initiated from the Blackberry side as a "receive".
1) set up phone as Manufacturer: -Other- and Model: GSMphone
2) Data service is Cingular WAP GPRS
3) In the network prefs, go to the Service called Cingular WAP GPRS, and click Details. Check the Query DNS box. Then click on "Script".
4) Here is my script:
Send: AT
Send CR
Wait For: OK
Send: AT&F0E0V1S0=0
Send CR
Wait For: OK
Send: AT+CGDCONT=1,"IP","WAP.CINGULAR"
Send CR
Wait For: OK
Send: ATD*99#
Send CR
Wait For: CONNECT
Delay: 0
End
Hope this helps, and that it works for more than just me
