I purchased an iPhone ~3 months ago (right when they came out) and I'm having some intermittent, odd errors. I'm on AT&T and live in the Denver area (in case it matters). When on the highway, the iPhone has a very hard time keeping a network connection. The only reason I care is I use Siri to call folks & that kind of thing - no, I'm not one of those texting road-hazards. Also, the wireless sync is CERTAINLY a moving target. It will start, but sometimes fail, and then cannot see my MBP until I reboot both the phone & recycle the wireless on the MBP (which is a brand-spanking new bada$$ machine, let me tell you). NONE of this is consistent. Overall, I'm very happy with the phone, but stuff like this gives me pause just because it smells a bit like a latent issue that could portend an early device death. What do the fine folks here think?
