I was on (unrooted) 4.3 and a coworker rooted me with safestrap. It seemed fine while on 4G, but once I got home on Wifi, I couldn't sync to my Google accounts, Dropbox, Amazon, My Backup Assistant, weatherbug ... On 4G, My Backup Assistant sync only 7 contacts (I've got around 1000). On 4G, the services seem to sync except for contacts. Last night, I backed up via My Backup Pro and did a force hard reset (pain in the butt). It seemed OK after that but then, after work when I got back on Wifi, it reverted to not syncing. HELP!!!!!
