I'm on the 1229 too and the GPS wouldn't lock either until I was on the move and then it locked. It took 5mins while driving but it finally locked for me.
On a side note: the time would not stay in my time time zone despite settings.
Flashing to 1230 now.
Check "automatic date and time" and leave "automatic time zonen" unchecked. Select time zone manually if necessary. It will stick when your data kicks in.
