I have added a note in the first post about removing unused themes. With the newer devices (8100, 8300, 8800, 8830) there are issues with memory allocation. When free memory gets too low the device will begin to delete emails, sms, and call logs. This can obviously be undesirable. Some of the vendor themes are almost 1Mb in size each and can take up considerable space.

Here is my suggestion:

Remove unwanted themes by simply removing them from the java folder. The java folder contains all the .cod's that get loaded to the device. Remove the unwanted .cod's and place them into another folder somewhere. Once you've removed the themes you don't want, simply plug in the device and run through application loader. It will remove the "unrecognized modules." If you want a theme back simply put it back into the java folder and do the same.

Personally, I have removed all the themes except the TMobile zen and the today plus (downloaded from BlackberryHELP.) I even removed the TMo faves app which gets loaded with the edited .alx's (even if you're not on TMo.)

It's just another way to free up memory to assist in the quest of no more deleted call logs/emails.

Theme .cod's are listed as:

net_rim_theme_100...
net_rim_theme_102a... etc.

The numbers below are the vendor ID's for each carrier and will help you identify which themes are which:


You can safely delete any of the below vendor-numbered themes. The size listed is an average size for that carrier's theme. As you can see a couple of them are quite big.

100=Tmobile 240kb
102=AT&T 769kb
104=Sprint 17kb
105=Verizon 572kb
107=Rogers 287kb
109=Bell 194kb
114=TMo UK 243kb
115=TIM 698kb
119=Orange 635kb
120=Vodafone 624kb
125=O2 349kb
129=Telefonica 30kb


You can also safely delete TMo myfaves apps if you don't use myfaves:

net_rim_bb_media_100_five_icon_library.cod
net_rim_tmo_five.cod

I don't recommend removing the bbdimension...themes as some of the above themes need these in order to run.
