Just got a 4 myself, and love it, although it's early days, so there may still be some problems that I haven't noticed. Plus - I'm a raving Apple fanatic, hence a bit biased So far though, I'd say it's a superb phone.
I think the early bugs (proximity sensor etc) are mostly gone - the only remaining one is the antenna issue. I did a quick check with my phone, and I do seem to be able to reduce the reception by gripping the phone in the 'magic' spot - but as I bought a case for it, I'm not really that fussed (and a note on whether to get a case - anyone buying an iPhone 4 is buying a phone with a glass front and a glass back. I figured a case made sense)
Anyway - I would highly recommend it.
