    thanks for the explanation! still a bummer that end users can't really tinker with it. hopefully it's something that rim is working on in their top secret os projects.

    is there something like a system bios on blackberries where a user could maybe repartition the space? or is that what you were saying is blocked off for security purposes?

    Just FYI,

    Internal Memory: 128 MB ROM/192 MB RAM (Actually MiB RAM)
    External Memory: microSD slot
    1GB of internal memory, an included 8GB memory card and an expandable microSD™ slot to store images, music, videos and presentations


    Random access memory (usually known by its acronym, RAM) is a form of computer data storage. Today it takes the form of integrated circuits that allows the stored data to be accessed in any order (i.e., at random). The word random thus refers to the fact that any piece of data can be returned in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data.

    This contrasts with storage mechanisms such as tapes, magnetic discs and optical discs, which rely on the physical movement of the recording medium or a reading head. In these devices, the movement takes longer than the data transfer, and the retrieval time varies depending on the physical location of the next item.

    The word RAM is mostly associated with volatile types of memory (such as DRAM memory modules), where the information is lost after the power is switched off. However, many other types of memory are RAM as well (i.e., Random Access Memory), including most types of ROM and a kind of flash memory called NOR-Flash.

    "App memory" (memory is a bit of a misnomer in these instances, but hey), means the available space for Application installation. When you install an app, the bulk of it (at least the executable parts), get installed in "App memory." Aside from this, the OS uses the app memory as a swap file to temporarily store data not held in RAM (usually if the program is idle), which is why the App Memory number fluctuates.

    Device memory is the total amount of on board storage space. Neither of these are "RAM", don't get them confused.

    The BB OS takes a chunk of the total device memory and allocates it as App memory. Our phones are advertised as having 1 gig of onboard memory, this is correct but ~128 megs of that is set aside specifically for Apps. Think of it like if you partitioned your hard drive and used C: for application installations, and D: for storage.

    Yes, it is possible for more to be allocated, but it must be done in a firmware (OS) update, to my knowledge there's nothing an end user can do.

    BTW, the system was setup like this for security reasons
    Nice! This explains it all pretty well. The device mem is the total amount of memory on the device, including app mem, which is just part of that 1GB total. Wish RIM would double the 128MB set aside specifically for apps (app memory) to 256MB. This would still leave 600+ MB of device memory that we don't use anyway.

    Don't know if you've seen the chipset yet.

    http://www.blackberryos.com/forums/b...pset-info.html

    ROM:type: Flash EEPROM
    ROM_capacity: 1152 MiB
    RAM;type: mobile DDR SDRAM
    RAM-capacity: 192 MiB

    This is accurate...we have been bitching about this from the beginning, wanting more app memory free.

    It is a wish of most to have an update that will allocate memory from the rest of the devices 1gb memory.
    The phone would crank if we could just get the access
