Some blogger find out the signal problems for the Apple's latest product--iPhone 4, do your guys found the problem also for your iPhone 4?

Are you referring to the issue they should be patching soon?

This issue has been confirmed even by Apple, and apparently even older phones like the 3GS are also affected (I haven't noticed because mine has been in a case since I got it). As bodiddly mentioned, Apple will be patching this soon with an update to iOS 4. Hopefully it is able to resolve the problem somewhat, though if it is indeed a hardware design issue I'm not sure how much a software solution will eliminate it.

And, of course, some shoddy lawyer is already getting a class-action lawsuit ready, even though the iPhone 4 has been out for less than a week.

I got my iPhone 3G to drop a single bar by damn near choking the phone with my hands, but that's about all I could get out of it. I tried to reduce reception to some iPhone 4 display models at the Apple store, but couldn't get them to drop any bars no matter how I held the phone.

The jury's still out on exactly how widespread this issue is.

If anyone thinks this is specific to the iPhone 4, they may be interested in watching a few of these videos (lifted from the comments section of MacNN, posted by _Rick_V_):
