l am using two devices right now while having this battery issue, the 4s and a Fierce XL. When I reactivated the XL, I think all the settings and app data synced across the devices. I need to check that though. On the SD card, if I unencrypt it, I think I can just remove it before the reset, then replace it afterwards and the reset device should be able to read it. I need to confirm that before I do it though.
if you have backups of everithing and the card is unencripted i would keep it there, becouse some apps when installing if they have backups in the SD card they will recover them.
ok, good to know. Thanks!
I don't know when I'll do it but I'll post the outcome after I do. Fingers crossed 🤞
