All items needing repair (other than IMP) should be sent to the manufacturer/distributor directly for service. B&H is not liable if the manufacturer/distributor fails to perform warranty service

You need to send it to Canon, being in warranty they will even cover the shipping I believe....

True they will cover shipping as they should for warranty items. However, my experience is that they might not offer it up front. You may need to ask for a prepaid shipping label. Also, the UPS labels I have received from Canon did not include any additional insurance.
Personally, if it's within 30 days I'd probably return it for a new replacement. It bugs me to buy something brand new just to turn around and send it in for repair.
The good news is Canon Service is outstanding!
Sounds like the 24-105 production line could use some QC work. I bought this lens late last December and it had a bubble in one of the elements. My second copy is at Canon right now because of the extreme out of focus--too much variance from the wide end to the tele end to AFMA (my body only stores one AFMA value).

Here is my version of Vinetting problem, anything think if my copy is normal? or i should send in Canon to fix too?

I've noticed this from time to time on my 24-105. When it is predominant in one corner over others it is always in a situation where the scene is brighter in one corner than the other(s). The darker corner(s) will exhibit the vignette; the lighter corners do not—or do so to a lesser degree.
As others have said, this is most likely to occur with stacked filters. Even with the "thin" filters, if I stack a circ-pol on my standard UV I can't use the 24mm setting on this lens w/o vignetting. W/o the polarizer I still have to be very careful. This is my number one pet peeve about the 24-105.

The 70-200 1:2.8 L II IS USM lens have the same problem, Canon SA said there is new firmware for the 70-200 lens expected this week to solve the vignetting problem, see also dpreview discussion
