I am using ip5 now,and I notice that I experience a really slow download speed in App Store coz it takes a long time to update or download new apps. The phone is connect to wifi network,and the speed test under wifi is 1.2MB/s and upload speed is 100KB/s (ATT Uverse 12Mb/s), so it proves that the phone works perfectly under my wifi network, but I have no idea why the download speed in APP Store is so slow. Is it iOS problem? but I am using 6.0.1 the latest firmware tho. Any hint to share?
