Default Loading 8700c 4.2 OS on unlocked formatted 8700g...

Please Login to Remove!

Hey guys, I acquired a used BlackBerry 8700g that is being used on a T-Mobile network. I have a Cingular/AT&T SIM card and want to use that in this T-Mobile 8700g. I am getting it unlocked tomorrow by T-Mobile (called and told them I need to use an international pay as you go SIM card) so I will be able to run my Cingular SIM card in this T-Mobile 8700g as far as I've read.

My only concern is that I want to upgrade to the new 4.2 OS and this is only available from Cingular/AT&T for the 8700c. If I use Javaloader to totally wipe my 8700g, will I be able to load the Cingular 4.2 OS for the 8700c onto this T-Mobile 8700g via Desktop Manager? Or are there hardware differences between the 8700g and 8700c? Thanks for any info!!!
