That explains it. I use maps. I tried to force loading the maps library using ClassLoader this morning - to no avail, as I figured anyway. Is there a (known) workaround? My perspective... 1.5 OTA update (T-Mobile) hasn't even hit my G1 yet and hopefully I don't have to bank on a future OTA update after that one. Could be months...
