Sprint servers are overloaded due to palm pre and EVO update hitting at the same time.
If this helped you hit thanks.
Doubt it's coming from Sprint's servers. Sprint just approves it, but it's most likely Palm still hosting it.
From what I understand if you have an unlocked phone the update comes from palm and if it is locked it comes from the carrier.
I believe the carriers just approve the updates. Palm hosts them.
Palm Vx -> Treo 600 -> Treo 700p -> Centro -> Pre (Launch Phone 06/06/09) -> AT&T Pre Plus with Sprint EVDO swap -> Samsung Epic 4G w/ Froyo
