Mobile size question... 325 or 480 ? iPhone or Android?

[Frank]

Please test the two links and tell me which fits best on your phone.
Please indicate type of phone: iPhone or Android.

This isn't a redirect question but an actual smartphone size question.

NO REDIRECT IN PLACE: The page is built on 480 (with default Antenna viewport) view on phone.

NO REDIRECT IN PLACE: The page is built on 325 with a custom added viewport of 325px view on phone.

the last one is better but you have something a fraction outside the 325px as I have to scroll sideways a few mm.
The top one I have to scroll heaps to see it all

That's so strange both are rock solid on my Android. NO side scrolling at all on either.

I just realised Frank the reason I have to scroll is because the browser on the phone is zooming in so once I pinch and zoom back out its fine but on the initial load it zooms the both sites

Still weird since we both are on Androids... I'll check on a iPhone later.
Thanks for testing,
