The images on any web page are blurred, low quality.

This just started when i came to europe. I had been using my iphone 3g to tether in the US for internet, all images on all pages were fine. I just got it jail broken and now images on the iphone as well as on the macbook (when it is tethered) are blurred. I have not tried with another source of internet on phone or the macbook.

Seems to me the problem is in the iphone after jailbreak.
