Pretty interesting....
 
I found this to be very interesting as the E62 and E50 are the only 2g v3's available.

The Nokia E61 (and Nokia E60, Nokia E70) are 3G phones and have a dual chip design with separate cellular and application side processor and memory, whereas the Nokia E62 (and Nokia E50) are 2G phones and have a single chip design with common processor and memory for cellular and application side.

In the Nokia E61 the applications must be loaded to the RAM for execution, whereas in the Nokia E62 they can be directly executed from their permanent location in Flash memory. Also the memory types are different between the two. So even though the Nokia E61 and the Nokia E62 look the same, the internal HW is different, which affects the performance and characteristics.

Nokia E62 (and Nokia E50): Single chip design / ARM9 235Mhz / 32MB SDRAM / 32 NOR + 128 NAND Flash / with XIP (eXecute In Place) support (execution from Flash)

Nokia E61 (and Nokia E60, Nokia E70): Dual chip design (with separate chip for cellular modem)

Details of the application side chip: ARM9 220Mhz / 64 DDR SDRAM / 128 NAND Flash / without XIP (must be loaded to RAM)


No mention of the missing themes in the app manager. I would think that would be a big bug as you have to enable hidden folders and find the files the old fashioned way
 
I would *guess* that being able to execute a program directly from flash storage would be way better than having to load it into RAM, as you wouldn't have to worry about running out of memory and having apps crash. RAM is limited and can run out, whereas with flash storage, not only do you have much more of it available (2GB on a 2GB SD Card), the app is already occupying its allocated space on the flash drive, and doesn't have to "grab" it from the system in order to run.

It would be like saying that if you're carrying around a backpack full of books on your back, you could somehow read any of them at any time without having to take them out and hold them in your hands (RAM).

Anyone want to correct me if I have this wrong?
 
I recall reading that the N73, for example, is faster in opening menus than the E50, yes? In this case, the dual-chip solution, albeit a tiny bit slower in clock frequency, is better?
