the ram issue sucks for us OG droid users. but i have the same problem you mentioned, happens sometimes when i get a call and it locks up. the odd thing is that the dialer is always in the foreground (-16 oom value) so it should be responsive... try compcache and see what happens. 256 ram should be good for a phone tho, iphone 3gs has 256 ram and i think iOS 4 was offered to 3gs users with its pseudo multitasking. so i know it can work, its just all memory management of the OS, and gingerbread seems to need better hardware..... problem is nothing is a worthy upgrade yet. galaxy s2 or bionic is what im waiting for.
