According to PreCentral, it would appear as if the next iteration of Palm’s webOS — version 1.4.5 — is to make its debut imminently. Carrier testing is nearly complete, they say, also noting that AT&T will be delaying the release of the updated operating system so soon after the release of their webOS devices themselves.
That said, not much else is known about when the update will actually be making its debut to handsets around the map. Could be this week, could be next, or a simply delay could push things back by weeks.
Certainly, we’ll have more information on this as it becomes available.
