i got mine as fast and fluid as an iPhone. i use ROM Toolbox Pro, a root only app but it works well. managed to change the minfree, VM Heap, tweak autostarts, etc and now it runs perfectly well. however unless the OP wants to root and take risks, this won't help his/her issue sadly. i had the same issues out of box as the OP though. out of box, it has very little internal storage, very little RAM, and too many apps = lag and crashing/ANRs
PrepaidGuy, do you know any way to disable the annoying 'no signal' alert? every Area51 ROM has it enabled and i cannot locate the sound anywhere. it's not in /media/audio at all. logcat seems to point to some 'DMApp' and 'DefaultPhoneNotifier' whenever it goes off. i also tried to post a thread about it in Android Area51 but there must be some limit on how long a post from a new member can be as it only posted two sentences instead of the entire post.
