How much memory does your 8700 normally have free during normal use? Mine has about 46.5MB's after a hard reset and then quickly bleeds out to about 43MB's. Anyone have more? less?
It all depends on how many applications you have installed and how many emails, contacts, appointments, etc, you have. As long as you have 1 or 2 MB free you will be fine. The BlackBerry automatically deletes the oldest messages when it needs to free up space.
No, it doesn't continue to drop. It usually sticks around 30mb. The drop is likely due to running programs that keep something in the memory or loads and keeps certain data, like BB Weather, etc.
