iphone 3g very laggy. Running on 3.1.2

Hi guys,

I am having some issues with my iphone 3g. A few months ago i accidentally updated the software to ios 4.2.1 and shortly after i experienced serious lag. I looked into downgrading it and finally was able to downgrade the software to 3.1.3 using Ireb. It seemed to have fixed it, but i was still experiencing lag. I decided to downgrade to 3.1.2 but its still lagging. Is there anything else i can do to fix the lag? Is there a common issue that causes this?

i just to have that problem, it ran better when i had minimal app's, and no tweaks from cydia. then i got a 3gs and no more lagging, so imagine what a iphone 4 would do for you.
