Can i flash RM-xxx phones with another RM-xxx files ?

[underp]

Hello everybody, i'm just introducing my self to this new hobby.

I've been playing around with my e63, and i would like to pimp
this baby and bring it back to life with some new cool apps.

The thing is, my phone is rm-449, and there is no 500.21.009 upgrade
yet for my code number, wich stars with 059343.

I've heard some good reviews with the 500, but i'm afraid to kill
my phone since the 500 series i can get are rm-437.

I've also notice with Navifirm that 500.21.009 is available in
rm-449 but applies for a different phone codes, not mine.


I'm planning to pull the trigger with JAF.


Any tips on the subject i will gladly aprecciate it.


Thank you very much.
