ok great thanks.

so two mistakes. one purely mine, the other i hadn't read anywhere!

1. when i followed the link to download gimgunlock, i grabbed v.001 not the latest. so gmaptools showed locked under details. i went and grabbed v3 and presto. still no joy on GPS... SO

2. i opened up javawa and immediately a warning: SD card must be formatted fat/fat32 (it was exfat, the default for windows 8!!!) a quick reformat and problem solved.

thanks, love this community and all the support!!
