Buying 2DS and just want to one query and get two quick confirmations.
1) If you can exploit everything through SDcard what are people using flash cards for?
2) 10.4-10.6 Cannot be downgraded, no exploits
3) 10.3 and lower are wide open and exploitable, no need for anything lower.
1- Full plug and play online updates, the lot (with Sky+) I dont know about Gateway?
2- I think you can get HBL on 10.4/5 but not D/G or CFW without hardmod.
3- Yes.
