WMExperts is reporting that there was some speculation that the reason for the AT&T delay of the WM6 Treo 750 update is due to issues with the Good Messaging service. This comes from various discussions on message boards that WMExperts links to. Below is an excerpt from that discussion:
A mention today in the 750 forum makes the third instance I have heard that the ATT WM6 upgrades are being held up by the delays of GMM 5.0. Sources say that the ROM has been ready for weeks now (as witnessed by the dozens of successful upgrades with the "leaked" ATT ROM at places like XDA). However, since the GetGood functionality is part of ATT's base ROM, and since GMM 4.x versions are supposedly incompatible with WM6, the whole shooting match is waiting on GMM 5.0 to be complete.
