No, they didn't make it seem worse. If I put the phone on my flat hand, and let the signal stabilize, I could drop the signal by about 16dB with one finger (as numerically shown on a jailbroken phone). This was often enough to terminate a call.
There was no "seem" about it - it was a bad design. If I could have gotten a refund AND gotten out of my carrier contract, I would have.
