the best way i can describe it is that its snug and fits almost exactly the way i want it. its tight enough where i dont feel the phone loose or rattling within the case and the bottom part is also tight enough where it does not just fall off randomly, but not so tight where i can not remove it...
Thanks for letting me know. That sounds much better than the way my Innocase fits. I guess I'll contact Seidio about sending it back for replacement.
As far as the 3G/3Gs Innocase goes, I completely agree with you. I used one for almost a year, and it was my favorite case for the iPhone 3G. It was thin enough to almost feel like an extension of the phone. I don't really get that feeling with the iPhone 4 version...but for me it isn't the thickness that bothers me, it's the fit.
Hopefully, the replacement case will fit a lot better. I'll post back when I receive it.
Update:
I just received my replacement case from Seidio, and it does fit slightly better than the first one. While it still feels loose (without the bottom of the case on, the phone will slide out easily), the bottom piece does lock into place better. It takes a little effort to get the case apart, and it no longer feels like it will open accidentally.
Also, I have noticed that different colors seem to fit differently. I ordered the blue Innocase II before I returned the gray one, and it fit much better. The blue case is very snug on the phone, and can be used with the bottom of the case taken off for docking. Even with the bottom piece off, the phone will not slide out of the case, until you pull it out. I think that this is the way the case is supposed to fit.
I would also like to mention that Seidio's customer support is excellent. They quickly approved my return and shipped my replacement within one day of receiving the old case. Since Seidio is located in Houston, TX and I live only about 30 miles away, the turn around time was especially fast...so your experience may vary.
