Ok /dev/mmcblk0p1 seems to be still there and is fat32. Now I think(90% sure) it's a case of filesystem corruption.

Please try running this command from xterm

fsck.vfat -a /dev/mmcblk0p1

Note this will run for a very long time so stick it to your charger and let it finish
after it's done restart your phone and check if MyDocs is back.

-------------------------Do this if MyDocs is still not showing up--------------------------------

If still no then go to fdisk again
Command (m for help): d
Partition number (1-3): 1
Command (m for help): n
press p to select primary partition
First cylinder(1-#####, default 1): 2
then again press enter to auto select

Command (m for help): press t
Partition number (1-5): Select 1
Hex code (type L to list codes): type 0c and press enter

Lastly press W to commit changes then reboot
