I just know that my phone is 8210 rom 5. But refer to the forum, I can only found that 8210 rom 5 can upgrade to 8890. Currently my phone is running a V5.26 software with 36 original tones . The phone's function is exactly same with original 8210. Just wish somebody can tell me how to upgrade it to 8890 and what things do i need and where to get it. Thanks.
