I upgraded to 4.1 using the Hong Kong version for my 7100G from Cingular. Upon doing this I get this message:

Warnings were encountered during the loading process:
The following database(s) could not be fully restored to your device:
Options 8 of 9 entries restored.

well that was one concern because when went through the process it removed some stuff I thought was needed. Like:
Unrecognized modules that will be removed:
net_rim_bb_explorer_resource
net_rim_bb_explorer_resource__en
net_rim_bb_explorer_resource__de
net_rim_bb_explorer_resource__hu
net_rim_bb_explorer_resource__pl
net_rim_bb_explorer_resource__cs
net_rim_bb_explorer_resource__es
net_rim_bb_explorer_resource__zh_CN
net_rim_bb_explorer_resource__fr
net_rim_bb_explorer_resource__it
net_rim_bb_explorer_resource__pt_BR
net_rim_font_millbank
net_rim_plazmic_math
net_rim_font_european_shared
net_rim_bb_profiles_tunes_builtintunes
net_rim_bb_address_book_repository_listener
net_rim_device_apps_games_brickbreaker240X260resou rces
com_plazmic_theme_reader

I used the default themes and only one is usable because when I choose anything other than "default" i get a error of:

java.lang.illegalargumentexception.

So please help so I can load themes or at least correct the problem with the existing ones.
