Have just worked out how to post GPS results on the go using the Ipad Mini... should also work for all Ipads.
Have seen some people on here before wanting to know how...
1- Jailbreak device
2 - download IFile and ICabMobile
3 - using photo sd card transfer cable (Lightning to SD, available at all apple stores) insert SD Card
4 - Close auto launch photo application
5 - Access SD Card through "Mount1" folder in Var/mnt directory in Ifile
6 - open GPS file with ICabMobile
7 - Using ICabmobile go to Ka72 and hit upload, your SBN file will be ready to upload and your away.
Heaps handy on the go and fits in your glove box...
