FYI: This is from a Sprint Community contact that usually posts about updates:
"It was supposed to be this week but saw some issues in the lab. If it is something that can be fixed quickly, then it should be soon. If not, more than likely a bundle with July patch."
He says his other contacts are out the rest of the week so he can't find out more detail.
I'd say it is a good thing because I'd imagine it is network related issues. Last thing we need is a modem update that is even buggier...
