Sorry for yet another thread, but my BB has been acting up lately. Sometimes I'll be browsing through my phone, not browsing the internet, but just general app usage and such, and the hourglass icon will show up and stay there for varying periods of time, usually several minutes or more. Sometimes this happens when my phone is locked as well, so it sometimes takes minutes just to unlock my phone. Any help is appreciated!

What OS version is on the device? Options > About > then read the third line

What's your File Free? Options > Status > then read the third line

Have you done a battery pull with the device turned on?

In computer terms, the CPU is processing a high priority task ahead of the medium priority tasks like updating the screen display.

The most common high priority task is memory management. If you notice an improvement after forcing a restart, that is the most likely explanation.

Optimizing the memory on the 64 Mb BlackBerry is essential to getting the best experience.

Sounds like you've got too many apps installed on your phone. Go to options -> Status. If the number next to File Free is smaller than 15,000,000 (and especially 12,000,000) you need to delete some themes/apps.
