No i dont have that issue..but I do know that the i860 has been 3 or 4 better software updates. You wanna go here:
Motorola iDEN - Product Support
and check the latest firmware update utility on your phone model. Then press #,*,MENU,Right arrow on your phone (as fast as you can), select UNIT INFO, then SOFTWARE, and see what version you have. If it dont match. Update it, download the firmware (you also need a data cable).
Latest i860 firmware: R1C.02.0
