Hi everyone. Has anyone noticed that the Appstore download & login are extremely slow (and failing most of the time) since about a week ago?

It is happening on these devices :
1) iPhone 4
2) iPad2
3) iTunes on Windows7

I am using Maxis Broadband + the MiFi device (have also tried an Aztech USB modem; same result). The internet speed for all other activities (web surfing, YouTube, emails, etc) are all OK. Speedtest.net is reporting >2Mbps download most of the time.

On Apple Appstore, listing/searching of apps are fast (normal); however when I try to login, it will take a long time/fail. If I am already login, then the app download will take a long time (usually >15 min) before it will begin (and then proceeding slowly; failing very often).

Oddly enough, updating of my subscribed podcasts (iTunes on Win7) are still speedy (as usual).
