so I updated my iphone 1st gen to 2.0 and pwned it unlocked.

I notice now that the volume of ipod doesn't seem as loud, tuned down a notch. Also the EQ settings are kinda weird as well. Before I used to be able to swicth from Rock EQ to R&B EQ and I would notice a difference. Now there is almost no difference if any.

anybody notice this as well and if this is an issue, what can I do to fix?
