First, I buy blackberry curve 9300 and put my ID, email@example.com. Then I buy new blackberry bold 9900 with the same ID, firstname.lastname@example.org. When I changed the ID for 9900, 9300 has changed to. How to make my blackberry ID independenly. Thanks.
It is not recommended to share a BBID with more than one BB SmartPhone...things that you report can happen. Rather, each BB should have a BBID of it's own.
Choose which of your two BBs will keep the BBID. WIPE the other one and, when you are starting it back up, create a new BBID for it rather than using the existing one.
Occam's Razor nearly always applies when troubleshooting technology issues!
