I do not have problem, but since apple offer the case free I applied for it, and I bought my iphone 4 after Sept 30. I think they are still sending it out, altho the cutoff is Sept 30.
i never really had any antenna problems with my iphone 4, and the 3gs drops more calls then the iphone 4. but if your really that worried just wait for the iphone 5 or the iphone 4g possibly iphone 4gs coming this summer as always.
