1.1.2 to 1.1.1 to 1.0.2 back to 1.1.1 experience

so i got this week 41 otb 4GB with 1.1.2

i downgraded to 1.1.1 and it stayed with the 4.02 BB
and it was running slow...sluggish...screen flickering and whatnot...

so i downgraded to 1.0.2...still with the 4.02 BB...
and still running like crap...got the baseband to the 3xx BB...and i thought it'd
run good...but nope...stil sluggish...late responsive on the touchscreen...scrolling is mad slow...anyway...

i upgraded to 1.1.1....same crap....restored 1.1.1 same crap...
everything on 1.1.1 installed and i was able to unlock with anysim 1.1
and still this phone runs like crap...
5 days of me doing this...

so i'm now upgrading to 1.1.2 and starting over...ggrrrr!!!

sorry...i had to vent....

i've done a bunch of 1.1.1 unlocks and even some 1.0.2's...
but this sucker is a piece of crap...and soem peope told me they were successful...

so, guess i got a bad phone, huh?

yes it might be a bad phone.... haven't u tried before the first downgrade process?

back at 1.1.2 now....
and sure enough...it's running as smooth as it should be...
no screen flickering, no sluggisness....

now...downgrade again...damn...!!!!

back at 1.1.1 with 4.02bb and running like crap.......

i tried a bunch of things....

1.0.2 fw and 3xxbb
1.1.1 fw and 4.01bb

reflashing the basebands...
u name it...
and the phone runs like crap...
it doesn't respond to tocuh commands smoothly...
so i'm back at 1.1.2 with the new BB and it responds as smoothy as anyother iphone i've had...

when i was at 1.0.2 fw 3xxBB i checked the bootloader and it's 3.9
and this is a otb week 41 4GB
