Grand fathered account Data blocked from working on android??

From my understanding on the old forums this popped up.  The issue is the data plan and how it's setup.  Apple changed how theirs worked more in line with Blackberry ways of networking.  That's why those two work with that plan.  Android has never worked, because of how they handle data.  It had something to do with data compression standards, and BIS.

There was a gigantic thread before the forum change.  T-Mobile has to modify protocols and could break things which may violate their grandfather agreements placed on legacy plans.
