1520 Denim bad coverage?

[pyl]

We live in an area with pretty bad coverage. Before Denim I used to have at least a couple of bars, but after updating my 1520 to Denim I'm having major problems getting any coverage at all and I'm missing calls all the time.

Is this a known issue? Is there anything I can do?

This may not necessarily be the update causing this but I have something you can try. Check This out.
