BlackBerry 7290 requires BlackBerryOS 3.8 and later. OS 3.8 and later has some performance degradation.
BlackBerryOS 3.7 -- Fastest (but only available for older BlackBerry models)
BlackBerryOS 3.8 -- Slower than both 3.7 and 4.0
BlackBerryOS 4.0 -- Faster than 3.8 but slower than 3.7
It just so happens the 7290 came with the older OS 3.8 by default (this still happened until recently)
Did you upgrade to BlackBerryOS 4.0? It helps greatly.
What version do you see at Options->About?
Once upgrading to the latest 4.0, not many people can tell the performance difference between a 728
0 running 3.7 and a 729
0 running 4.0. Give that a try!
Also, when you open many applications at the same time on the 7290 and multitask using
+Esc, the model 7290 should
be much faster than the 7280, because of the extra memory (Double the memory, 32MB flash for storage, and more static RAM for program execution)
So essentially, some things are slower and some things are faster, but it shouldn't be a dramatic difference, once you upgrade to the latest OS4 because 3.8 is essentially a really slow "beta" of 4.0.
