Of course, memory is used, I don't think that it is possible otherwise.
this is an example (half day of usage)
switch from Dimension L to Verizon (example)
give it 15sec to "settle"
switch back to Dimension L

this absolutely makes sense with any GUI. To speed up graphical screen loading, icons and everything graphical that can, is cached.
I assume that you are using windows, if so take look at icon cache. This also can be cleaned. In case of windows big cache will burden RAM (and disk, not a problem nowadays as disks are huge in comparison to the disk size). Cleaning cache (deleting) will release memory taken. Same applies to OS X, linux but in different extend of course.
BB OS icon/graphical UI caching contributes (it seems) to memory leakage. Though no tool provided to clean it, one can clean this by switching themes. This indicates that RIM is aware of the problem (windows will not provide such option, currently no need to in past this also was a problem with earlier OS versions, same applies to OS X and linux (KDE, Gnome) or Solaris).
reacher graphic, more caching so more memory released after some time.
Reboot does exactly the same, clears caching (GUI, logs?, browser cached activity and such).
I have upgraded to 188.8.131.52/149 on Pearl. If earlier versions of Pearl OS will not clean theme/icon cache without reboot, then this only means that it is worth to update OS.
I am not sure why would you suggest restarting OS after switching theme.
I am not really fan of rebooting. I am using computers since mid 70' (mainframes then). Unless stability or speed is affected, I don't see any point of frequent OS rebooting.
Five days ago I updated OS to 4.3 using yours very nice howto and info provided by Redflea http://www.blackberryforums.com/gene...81-alltel.html
I don't see any instability signs or slowdowns after five days. Memory just after update was at 22.5k bytes, since then after each cleaning it hovers at 21k bytes.
I am not intending to reboot unless forced to do so.
