This is the thing putting me off getting an iPhone 4. I'm 100% anti-case on iPhones but if this bit of plastic is actually needed to get a decent signal then I don't know if I can force myself to upgrade
i just designed my own @ gelaskins. covers some of the parts for the reception issue and maintains the look.
$20 all in aswell, much better imo
I've just purchased one of these:

For the sum of £8.47.
Once I get it I shall post a few photos of it.
Just ordered that as a quick fix.
