The geocaching proximity alert seems to be working nicely now with large .ggz files. Tested it with a .ggz containing almost 10000 caches. No boot problems so far.
Seems prudent to wait if they haven’t even claimed to address issues with the last couple of versions.
No choice I guess if you were one of those with bricked units.
Ohh.. you have to copy the update file to the disk manually haha!
