App GPS accuracy not as good as Maps

[madeyjay]

So here's the deal: wrote an iPhone app that uses core location using kCLLocationAccuracyBest.

I've installed the app on a few iPads and iPod Touches for testing. Everything works fine.

I've installed the app on a few iPhones, results are unpredictable. The iPhones are connected via Wi-Fi (not 3G), and the locations being returned are WAY off.

BUT, if I close my app and pull up the Maps app, the location is spot on.

Again, the same same code is working fine on the iPads and iPod Touches. What could be the issue here? Is it possible for the 3G to throw off the GPS, even if the device is explicitly connected via Wi-Fi?

Am I taking crazy pills?

I'm experiencing the same issue. Did you ever resolve this?
