MSP-FET430UIF Firmware Update

I do not want to spread rumors. Instead, I would like to hear someone here to clear this.

What I heard is, CCE may offer to update the firmware inside the user’s MSP-FET430UIF. But if you accept that offer, your MSP-FET430UIF will no longer work for IAR or other third party software tools. I heard that even if you made a backup copy of the firmware of the MSP430F1611 inside the tool and restored it, it still would not work. They suspect that the EEPROM for the TUSB3410 inside the tool must also be restored to work for IAR.

I am using IAR and intend to switch to CCE. But I would like to be able to still use IAR for my old projects. Is this a one-way street? Do I need to use two different MSP-FET430UIF’s? (One for CCE and one for IAR?)
